Beneficios de los segmentos Express
-
Los segmentos expresos son una abstracción de enrutamiento de segmentos (SR) de una ruta subyacente. Los segmentos Express facilitan el establecimiento de rutas de SR de extremo a extremo utilizando cualquier tecnología subyacente. La tecnología subyacente actualmente admitida es RSVP-TE y SR-TE. El segmento expreso a través de la base RSVP-TE se explica a continuación.
En Figura 1, el dominio 2 aprovecha sus LSP subyacentes RSVP-TE para la administración de ingeniería de tráfico y presenta esos LSP RSVP-TE subyacentes como segmentos expresos a los dominios adyacentes (dominio 1 y dominio 3), lo que permite el establecimiento de rutas de SR-TE de extremo a extremo.
Figura 1: SR-TE de extremo a extremo de múltiples dominios con base RSVP
-
Los segmentos Express reducen implícitamente el tamaño de la lista de segmentos de SR comprimiéndolos (listas de segmentos) a, como mínimo, un ID de segmento (SID)/etiqueta por dominio. Esto resulta útil cuando de otro modo, las restricciones de ingeniería de tráfico de extremo a extremo darían como resultado una lista de segmentos que excede las capacidades de imposición de etiquetas del enrutador de entrada. Esto también resulta beneficioso cuando uno o más dominios ya están implementando SR-TE para la administración de rutas de ingeniería de tráfico.
En Figura 2, puede ver que el dominio 2 usa SR-TE y cómo el uso de segmentos express permite que el dispositivo PE1 use tres etiquetas para atravesar la red multidominio en lugar de cinco.
Figura 2: SR-TE de extremo a extremo de múltiples dominios con pila de etiquetas reducida
-
Los segmentos Express permiten a los operadores presentar una abstracción de la red a dominios adyacentes y/o sistemas de capa superior.
Para establecer una ruta de ingeniería de tráfico a través de una serie de dominios interconectados o una red multidominio, es necesario tener una cierta cantidad de información de ingeniería de tráfico sobre cada dominio de red. La abstracción de topología permite el uso de políticas para conectarse entre dominios. La abstracción de topología no ofrece necesariamente todas las opciones de conectividad posibles, sino que presenta una vista de la conectividad potencial de acuerdo con las políticas que determinan cómo se deben usar los recursos del dominio. El dominio podría construirse como una malla de segmentos expresos de nodo de borde a nodo de borde.
Mediante el uso Figura 2de , la vista de PE2 de un sistema de ingeniería de tráfico de extremo a extremo se representa en su base de datos de ingeniería de tráfico local, tal como se muestra en Figura 3.
Figura 3: Dominio de ingeniería de tráfico abstraído
Casos de uso
En esta sección se describen algunos casos de uso para establecer la conectividad SR-TE de extremo a extremo. RFC7926 presenta un conjunto completo de terminología y casos de uso junto con una arquitectura para facilitar el intercambio de información de nodos y vínculos de ingeniería de tráfico entre dominios. A medida que las redes de los proveedores de servicios se expanden debido al crecimiento continuo, las redes de múltiples dominios son cada vez más frecuentes. En estas redes de varios dominios, es necesario establecer una ruta de ingeniería de tráfico de extremo a extremo entre uno o más dominios desde un origen hasta un destino

Conectividad SR-TE intra e interdominio mediante segmentos Express
Los segmentos Express tienen la capacidad de abstraer información de ingeniería de tráfico cuando el intercambio de información de enrutamiento ocurre entre dominios. La información de ingeniería de tráfico utilizada como criterio para la selección de rutas son los datos relacionados con los nodos y enlaces de ingeniería de tráfico. La información de ingeniería de tráfico puede ser métricas de vínculo como IGP, ingeniería de tráfico, latencia o atributos de vínculos administrativos como afinidades. Los segmentos Express se describen mejor como enlaces de ingeniería de tráfico virtual que facilitan la abstracción de LSP subyacentes.
Siguiente salto bajo demanda mejorado
El próximo salto bajo demanda (EODN) mejorado (también conocido como políticas de SR activadas por BGP) facilita el aprovisionamiento dinámico de políticas de SR-TE de extremo a extremo, con restricciones, a la llegada de rutas de servicios. En redes grandes con cientos de dispositivos de PE, crear y mantener políticas de ingeniería de tráfico en cualquier PE de entrada para cada PE de salida es un desafío. Considerar los colores de los servicios específicos (por VPN o por grupo de prefijos) hace que las cosas sean aún más complicadas y difíciles de mantener y solucionar. El SR-TE activado por BGP aborda la tarea mediante la creación automática de túneles de SR dinámicos basados en plantillas preconfiguradas. No es necesario aprovisionar PE de entrada con configuración para cada PE de salida.
¿Cómo funciona Express Segment?
Los segmentos Express se pueden utilizar para establecer rutas de ingeniería de tráfico de extremo a extremo entre redes de ingeniería de tráfico interconectadas. Los segmentos Express (también conocidos como vínculos de ingeniería de tráfico virtual) se generan dinámicamente a través de políticas que coinciden con los LSP subyacentes. Los segmentos Express y la topología abstracta correspondiente (requerida por RFC7926) se generan con políticas.
Para aplicar una directiva, incluya la policy policy-name instrucción configuration en el nivel de jerarquía [edit protocols express-segment traffic-engineering].
Nota:
El policy-name es opcional. Si no se define un nombre de directiva, la directiva importa implícitamente todos los segmentos expresos a la base de datos de ingeniería de tráfico local. Una plantilla de segmento express crea automáticamente una asignación individual de enlaces expresos.
Para configurar el segmento rápido, incluya la instrucción de express-segment configuración en el nivel de jerarquía [edit protocols].
Hagamos referencia y Figura 1 usemos el par de LSP RSVP-TE que se muestran entre los nodos de borde C1 y C4 y cómo se generan los segmentos expresos que representan los LSP subyacentes. En Figura 4, se crea una política para representar dos LSP RSVP-TE (oro y oro líquido) como un único segmento expreso.
Figura 4: Un par de RSVP-TE LSP representados como un segmento Express
A continuación se muestra un ejemplo de política en la que el nombre de la directiva coincide mediante una expresión regular y el extremo de los LSP RSVP-TE:
protocols {
express-segment-set gold-exp-seg {
policy gold;
}
}
policy-options {
policy-statement gold {
from {
route-filter 10/8 {
install-next-hop lsp-regex *gold;
}
}
then accept;
}
}
En la siguiente salida de ejemplo, puede ver que el segmento express recién creado (Gold-Exp-Set-192.168.1.4) junto con los atributos de ingeniería de tráfico se heredan de los túneles RSVP-TE subyacentes:
user@C1#show express-segments name gold-exp-seg-192.168.1.4 detail

TE-Metric: 30, IGP-Metric: 30

SRLGs: None
BW: 500Mbps
Puede observar lo siguiente en la salida:
-
Nomenclatura automática del segmento express (
Gold-Exp-Set-192.168.1.4). -
Los atributos de ingeniería de tráfico (ancho de banda, métricas, grupos de administración, SRLG) de las RSVP-LSP subyacentes son heredados por el segmento expreso.
-
El segmento express es un enlace de ingeniería de tráfico no numerado y se ha agregado a la base de datos de ingeniería de tráfico.
-
La etiqueta 19 se asignó e instaló en la
mpls.0tabla de reenvío como SID de adyacencia para el vínculo de ingeniería de tráfico virtual de SR.
A continuación se muestra un ejemplo en el que el destino LSP SR-TE coincide:
protocols {
express-segments {
segment-set set1sr {
membership-policy expresspolsr1;
}
traffic-engineering;
}
policy-options {
policy-statement expresspolsr1 {
from {
protocol spring-te;
route-filter 3.3.3.3/32 exact;
}
then accept;En la siguiente salida de ejemplo, puede ver el segmento express (set1sr-3.3.3.3) recién creado de los túneles subyacentes SR-TE sin color:
user@C1show express-segments detail Name: set1sr-3.3.3.3 To: 3.3.3.3, Type: Dynamic (Set: set1sr) Label: 16 (Route installed in mpls.0, TED entry added) Status: Up (ElapsedTime: 5d 20:37:08) LinkAttributes: LocalID: 2147483649 TE-Metric: 20, IGP-Metric: 20 BW: 0bps UnderlayPaths: 1 SRTE LSP: lsp1to3_sr TE-Metric: 0, IGP-Metric: 0 BW: 0bps
¿Cómo se anuncian los segmentos Express?
Los segmentos Express se anuncian a través de límites de dominio o a controladores de nivel superior y elementos de computación de ruta (PCE) mediante el estado de vínculo BGP. Cuando se intercambia información a través del estado del vínculo BGP, las extensiones para el estado del vínculo BGP se utilizan para anunciar segmentos expresos como vínculos de ingeniería de tráfico. Los enlaces de ingeniería de tráfico de segmento expreso y otros enlaces de ingeniería de tráfico normales aparecen en la base de datos de estado de vínculos de ingeniería de tráfico de cualquier LSR en la red y se utilizan para calcular rutas de ingeniería de tráfico de extremo a extremo. Las entradas de la base de datos de ingeniería de tráfico del segmento expreso se importan y exportan desde la tabla fo el lsdist.0 anuncio a través del estado del vínculo BGP con la siguiente configuración de importación y exportación de bases de datos de ingeniería de tráfico:
protocols {
mpls {
traffic-engineering {
database {
import {
l3-unicast-topology {
bgp-link-state;
}
policy es_2_bgpls;
}
export {
policy bgpls_2_ted;
}
}
}
}
bgp {
group te-peers {
family traffic-engineering {
unicast;
}
export abstract-topo;
}
}
}
Figura 5 proporciona una representación visual de cómo se reflejan los vínculos y nodos de ingeniería de tráfico entre la base de datos de ingeniería de tráfico local y la lsdist.0 RIB que BGP-LS usa para la publicidad. Como se ilustra, hay varios puntos de vinculación de políticas.
Figura 5: Segmentos de Advertising Express
¿Cómo utiliza un elemento de computación de ruta los segmentos Express?
La directiva de exportación de estado de vínculo BGP es un lugar eficaz para crear una topología abstracta o personalizada que se anuncia a un par de ingeniería de tráfico. Por ejemplo, es posible que desee anunciar sólo el segmento express y los vínculos y nodos TE del dominio 3 a PE2, de forma que la topología de ingeniería de tráfico se abstraiga como se muestra en Figura 6. A continuación, PE2 utiliza la vista abstracta para el cálculo de rutas de extremo a extremo.
Figura 6: Abstracción del dominio de ingeniería de tráfico 2 con Express Segment
A continuación se muestra un ejemplo de configuración de una directiva de exportación de estado de vínculo BGP en C1:
policy-options {
policy-statement abstract-topo {
from {
traffic-engineering {
protocol express-segment;
ipv4-prefix {
as 3;
}
}
}
then accept;
}
}
A continuación se muestra un ejemplo de configuración de política de SR en el enrutador PE2 para establecer una ruta de extremo a extremo de varios dominios de PE2 a PE3:
protocols {
source-packet-routing {
source-routing-path pe2-to-pe3 {
to 192.168.70.1;
color 10;
primary {
sl1 {
compute {
profile_any-path;
}
}
}
}
}
}
La ruta de extremo a extremo resultante se representa en Figura 7. Puede ver que el SID de adyacencia del segmento express (etiqueta 19) se utiliza en la lista de segmentos de SR, lo que hace que el tráfico tenga un equilibrio de carga en los LSP RSVP-TE de oro y oro líquido dentro del dominio 2.

Descripción general
La siguiente topología (Figura 8) muestra dos dominios SR-TE (AS100 y AS300) que ejecutan EBGP-LS interconectados a través de un dominio RSVP-TE (AS200):
Topología
Figura 8: Conectividad SR-TE entre dominios mediante segmentos Express
En esta topología, se establece una ruta de SR-TE de extremo a extremo entre el enrutador PE1 y el enrutador PE2. Los segmentos de ingeniería de pares de salida (EPE) se definen en enrutadores PE1 y PE2 para dirigir el tráfico hacia sus nodos de borde directamente conectados BN1/BN2 y BN3/BN4, respectivamente. Los segmentos EPE definidos en los nodos de borde se anuncian internamente a través del estado de vínculo BGP. Estos dos dominios de SR-TE están interconectados a través del dominio (AS200) que aprovecha los LSP de RSVP-TE para el establecimiento de rutas internas.
Los nodos de borde del dominio AS200 facilitan la abstracción de información de SR-TE entre dominios. Los segmentos Express se crean en nodos de borde (BN1, BN2, BN3 y BN4). Los segmentos Express se crean en una relación uno a uno con los LSP RSVP-TE subyacentes y todos los segmentos express se insertan en la base de datos TE local del nodo fronterizo para su posterior anuncio de estado de vínculo BGP. El dominio AS200 aprovecha las capas subyacentes de LSP RSVP-TE para la administración de TE y presenta esas LSP RSVP-TE subyacentes como segmentos expresos a los dominios AS100 y AS300, lo que permite que los dominios tengan conectividad LSP SR-TE de extremo a extremo.

Configurar R4 (enrutador BN2)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R4:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R4#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Configurar R6 (enrutador BN4)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R6:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R6#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Configurar R7 (enrutador PE2)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R7:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R7#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Verificar los anuncios del segmento Express
Propósito
Compruebe que el nodo de origen anuncia segmentos expresos a sus vecinos LS de eBGP/iBGP.
Acción
Desde el modo operativo, ejecute los siguientes comandos:
-
show route table lsdist.0: compruebe que se están anunciando los segmentos express del BGP-LS de RIB. -
show route advertising-protocol bgp neighbor: verifique que los segmentos expresos se envíen a los vecinos de eBGP/iBGP LS.

Significado
-
En la
show route table lsdist.0salida, BGP anuncia las rutas en la tabla de enrutamiento. La tabla de enrutamiento se crea a partir de la base de datos TE. Puede ver los enlaces de segmentos expresos (EXPRESS-SEG/6) y los enlaces EPE (BGP-LS-EPE:0 }/1216). -
En la
show route advertising-protocol bgp 10.2.2.2salida, puede ver a qué se está anunciando R1. Los segmentos expresos se insertan en la base de datos TE, que se copia en RIB. BGP-LS anuncia la RIB al enrutador par. En el par, la información de RIB recibida se copia en la base de datos local. La política de este ejemplo solo anuncia segmentos expresos y segmentos EPE.
Comprobar la información de topología de TE
Propósito
Compruebe que los nodos de entrada reciben información de topología de TE a través de eBGP/iBGP LS.
Acción
Desde el modo operativo, ejecute los siguientes comandos:
-
show route receive-protocol bgp neighbor: verifique que los segmentos expresos se reciban de los vecinos de eBGP/iBGP LS. -
show route table lsdist.0: compruebe que los segmentos de Express estén en la RIB BGP-LS. -
show ted database topology-type l3-unicast detail: verifique que los segmentos expresos se importen a la base de datos de TE del enrutador de entrada. -
show spring-traffic-engineering lsp: compruebe que la política de SR de extremo a extremo se haya calculado e instalado correctamente.

Descripción general
La siguiente topología (Figura 9) muestra dos dominios de SR-TE (AS100 y AS300) que ejecutan EBGP-LS interconectados a través de otro dominio de SR-TE (AS200):
Topología
Figura 9: Conectividad SR-TE entre dominios mediante segmentos Express a través de la base SR-TE
En esta topología, se establece una ruta de SR-TE de extremo a extremo entre el enrutador PE1 y el enrutador PE2. Los segmentos de ingeniería de pares de salida (EPE) se definen en enrutadores PE1 y PE2 para dirigir el tráfico hacia sus nodos de borde directamente conectados BN1/BN2 y BN3/BN4, respectivamente. Los segmentos EPE definidos en los nodos de borde se anuncian internamente a través del estado de vínculo BGP. Estos dos dominios de SR-TE están interconectados a través del dominio (AS200) que aprovecha los LSP de SR-TE para el establecimiento de rutas internas.
Los nodos de borde del dominio AS200 facilitan la abstracción de información de SR-TE entre dominios. Los segmentos Express se crean en nodos de borde (BN1, BN2, BN3 y BN4). Los segmentos Express se crean en una relación uno a uno con los LSP de SR-TE subyacentes y todos los segmentos express se insertan en la base de datos de TE local del nodo de borde para su posterior anuncio de estado de vínculo BGP. El dominio AS200 aprovecha las subcapas de LSP SR-TE para la administración de TE y presenta esas LSP de SR-TE subyacentes como segmentos expresos a los dominios AS100 y AS300, lo que permite que los dominios tengan conectividad LSP SR-TE de extremo a extremo.
En la tabla siguiente se describen los dominios, enrutadores y conexiones de la topología:

Configurar R0 (enrutador PE1)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R0:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R0#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Configurar R1 (enrutador BN1)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R1:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R1#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Configurar R4 (enrutador BN2)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R4:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R4#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Configurar R2 (enrutador intermedio)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R2:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R2#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Configurar R3 (enrutador BN3)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R3:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R3#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Definir un mecanismo para crear automáticamente (dinámicamente) segmentos expresos e insertarlos en la base de datos TE para que puedan ser anunciados a través de BGP-LS. En este ejemplo, se crean segmentos expresos para todos los túneles de SR subyacentes automáticamente. Esto se hace configurando una plantilla con una política y, a continuación, se crean automáticamente segmentos expresos en función de las políticas.

Configurar R6 (enrutador BN4)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R6:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R6#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Definir un mecanismo para crear automáticamente (dinámicamente) segmentos expresos e insertarlos en la base de datos TE para que puedan ser anunciados a través de BGP-LS. En este ejemplo, se crean segmentos expresos para todos los túneles de SR subyacentes automáticamente. Esto se hace configurando una plantilla con una política y, a continuación, se crean automáticamente segmentos expresos en función de las políticas.

Configurar R7 (enrutador PE2)
Procedimiento paso a paso
En el ejemplo siguiente, debe explorar por varios niveles en la jerarquía de configuración. Para obtener información acerca de cómo navegar por la CLI, consulte Uso del editor de CLI en modo de configuración en la Guía del usuario de CLI.
Para configurar el dispositivo R7:
-
Configure el modo de servicios de red como IP mejorada. IP mejorada establece los servicios de red del enrutador en Protocolo de Internet mejorado y utiliza capacidades de modo mejorado.
[edit] user@R7#set chassis network-services enhanced-ip
Después de configurar la
enhanced-ipinstrucción y confirmar la configuración, aparece el siguiente mensaje de advertencia solicitándole que reinicie el enrutador:'chassis' WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior. commit complete
El reinicio abre los FPC en el enrutador.
-
Configure las interfaces para habilitar el transporte IP, MPLS e ISO.

Verificación
Para confirmar que la configuración funciona correctamente, realice las siguientes tareas:
- Verificar el segmento Express
- Verificar los anuncios del segmento Express
- Comprobar la información de topología de TE
Verificar el segmento Express
Propósito
Compruebe que los segmentos expresos se crearon correctamente.
Acción
Desde el modo operativo, ejecute los siguientes comandos:
-
show express-segments detail: permite verificar si se han creado los segmentos expresos. -
show ted database topology-type express-segments detail: verifique que los segmentos expresos recién creados estén insertados en la base de datos TE. -
show route table mpls.0 protocol express-segments: verifica si se han creado las entradas de reenvío.

En el
show route table mpls.0 protocol express-segmentsresultado, puede ver la etiqueta de segmento express (16). Debido a que el segmento express es una construcción que se basa en los LSP subyacentes, la etiqueta del segmento express se cambia a las etiquetas SR-TE subyacentes (801003).
Verificar los anuncios del segmento Express
Propósito
Compruebe que el nodo de origen anuncia segmentos expresos a sus vecinos LS de eBGP/iBGP.
Acción
Desde el modo operativo, ejecute los siguientes comandos:
-
show route table lsdist.0: compruebe que se están anunciando los segmentos express del BGP-LS de RIB. -
show route advertising-protocol bgp neighbor: verifique que los segmentos expresos se envíen a los vecinos de eBGP/iBGP LS.

Significado
-
En la
show route table lsdist.0salida, BGP anuncia las rutas en la tabla de enrutamiento. La tabla de enrutamiento se crea a partir de la base de datos TE. Puede ver los enlaces de segmentos expresos (EXPRESS-SEG/6) y los enlaces EPE (BGP-LS-EPE:0 }/1216). -
En la
show route advertising-protocol bgp 10.2.2.2salida, puede ver a qué se está anunciando R1. Los segmentos expresos se insertan en la base de datos TE, que se copia en RIB. BGP-LS anuncia la RIB al enrutador par. En el par, la información de RIB recibida se copia en la base de datos local. La política de este ejemplo solo anuncia segmentos expresos y segmentos EPE.
Comprobar la información de topología de TE
Propósito
Compruebe que los nodos de entrada reciben información de topología de TE a través de eBGP/iBGP LS.
Acción
Desde el modo operativo, ejecute los siguientes comandos:
-
show route receive-protocol bgp neighbor: verifique que los segmentos expresos se reciban de los vecinos de eBGP/iBGP LS. -
show route table lsdist.0: compruebe que los segmentos de Express estén en la RIB BGP-LS. -
show ted database topology-type l3-unicast detail: verifique que los segmentos expresos se importen a la base de datos de TE del enrutador de entrada. -
show spring-traffic-engineering lsp: compruebe que la política de SR de extremo a extremo se haya calculado e instalado correctamente.

Significado
-
En la
show route receive-protocol bgp 192.168.1.2salida, muestra las rutas que ha recibido el enrutador de entrada (R0) desde el vecino BGP, que describe el segmento express (vínculos TE virtuales). -
En el
show route table lsdist.0resultado, muestra las rutas que ha recibido el enrutador de entrada (R0) y si están insertadas en la lsdist.0 RIB. También muestra si la lsdist.0 RIB se copia en la base de datos local de TE. -
En la
show ted database topology-type l3-unicast detailsalida, las rutas se copian en la base de datos local de TE. El set1sr-10.3.3.3 es un segmento expreso con punto final como 3.3.3.3 y se creó correctamente en R1. R1 ha anunciado el segmento express y R0 lo ha insertado en la base de datos local de TE. También puede ver los segmentos EPE (epe_adj1_toR7). -
En el
show spring-traffic-engineering lspresultado, puede ver que las políticas de SR están activas. Muestra que ahora puede calcular una política de SR de extremo a extremo (R0 a R7) de varios dominios. -
En el
show spring-traffic-engineering lsp detailresultado, puede ver las etiquetas seleccionadas. En el computelsp1 LSP, la etiqueta 7101 es un segmento EPE, 16 es el segmento expreso y 7137 también es un segmento EPE. Muestra que ahora puede calcular una política de SR de extremo a extremo (R0 a R7) de varios dominios.
