Benefícios dos segmentos express
-
Segmentos express são uma abstração de roteamento por segmentos (SR) de um caminho underlay. Segmentos express facilitam a criação de caminhos SR de ponta a ponta usando qualquer tecnologia underlay. A tecnologia underlay atualmente suportada são RSVP-TE e SR-TE. O segmento expresso por underlay RSVP-TE é explicado abaixo.
In Figura 1, o Domain 2 utiliza seus LSPs underlay RSVP-TE para gerenciamento de engenharia de tráfego e apresenta esses LSPs RSVP-TE underlay como segmentos expressos para os domínios adjacentes (Domínio 1 e Domínio 3), permitindo assim o estabelecimento de caminhos SR-TE de ponta a ponta.
Figura 1: SR-TE multi-domínio de ponta a ponta com underlay RSVP
-
Segmentos expressos reduzem implicitamente o tamanho da lista de segmentos SR comprimindo-os (listas de segmentos) para, no mínimo, um ID de segmento (SID)/rótulo por domínio. Isso se torna útil quando restrições de engenharia de tráfego de ponta a ponta resultariam em uma lista de segmentos que excede os recursos de imposição de rótulos do roteador de entrada. Isso também se torna benéfico quando um ou mais domínios já estão implementando o SR-TE para o gerenciamento de caminhos projetados para tráfego.
Em Figura 2, você pode ver que o Domínio 2 está usando SR-TE e como o uso de segmentos expressos permite que o dispositivo PE1 use três rótulos para atravessar a rede multi domínio em vez de cinco.

-
Segmentos express permitem que os operadores apresentem uma abstração da rede a domínios adjacentes e/ou sistemas de camada superior.
Para estabelecer um caminho projetado de tráfego por uma série de domínios interconectados ou redes multi domínio, é necessário ter uma certa quantidade de informações de engenharia de tráfego sobre cada domínio de rede. A abstração de topologia permite que o uso de políticas se conecte entre domínios. A abstração de topologia não necessariamente oferece todas as opções de conectividade possíveis, mas apresenta uma visão de conectividade potencial de acordo com as políticas que determinam como os recursos de domínio precisam ser usados. O domínio poderia ser construído como uma malha de nó de borda para segmentos expressos de nós de fronteira.
Usando Figura 2a visão do PE2 de um sistema de engenharia de tráfego de ponta a ponta está representado em seu banco de dados de engenharia de tráfego local, conforme mostrado em Figura 3.
Figura 3: Domínio de engenharia de tráfego abstrato
Casos de uso
Esta seção descreve alguns casos de uso para estabelecer conectividade SR-TE de ponta a ponta. RFC7926 introduz um conjunto abrangente de casos de uso e firewall, juntamente com uma arquitetura para facilitar a troca de informações de enlaces de engenharia de tráfego e nós entre domínios. À medida que as redes dos provedores de serviços estão se expandindo devido ao crescimento contínuo, as redes multi domínio estão se tornando mais prevalentes. Nessas redes multi domínio, é necessário estabelecer um caminho projetado de tráfego de ponta a ponta entre um ou mais domínios de uma fonte a um destino
Conectividade SR-TE intra e inter domínio usando segmentos express
Os segmentos express têm a capacidade de abstrair as informações de engenharia de tráfego quando a troca de informações de roteamento acontece entre domínios. As informações de engenharia de tráfego usadas como critério para a seleção de caminhos são os dados relacionados a nós e links projetados para tráfego. As informações de engenharia de tráfego podem ser métricas de enlaces como IGP, engenharia de tráfego, latência ou atributos de enlace administrativo, como afinidades. Os segmentos express são melhor descritos como links de engenharia de tráfego virtual que facilitam a abstração de LSPs underlay.
Next-hop aprimorado sob demanda
O Next-hop sob demanda aprimorado (EODN) (também conhecido como políticas SR desencadeadas pelo BGP) facilita o provisionamento dinâmico das políticas sr-TE de ponta a ponta, com restrições, após a chegada de rotas de serviços. Em grandes redes com centenas de dispositivos pe criando e mantendo políticas de engenharia de tráfego em qualquer PE de entrada para cada SAÍDA PE é desafiador. Considerar as cores de serviços específicos (por VPN ou por grupo de prefixos) torna as coisas ainda mais complicadas e mais difíceis de manter e solucionar problemas. O BGP acionou o SR-TE para a tarefa criando automaticamente túneis SR dinâmicos com base em modelos pré-configurados. Não é necessário provisionar PEs de entrada com configuração para cada SAÍDA PE.
Como funciona o segmento Express?
Segmentos express podem ser usados para estabelecer caminhos projetados de tráfego de ponta a ponta entre redes projetadas de tráfego interconectadas. Segmentos express (também conhecidos como links de engenharia de tráfego virtual) são gerados dinamicamente por meio de políticas que correspondam aos LSPs underlay. Segmentos expressos e a topologia abstrata correspondente (exigida por RFC7926) são gerados com políticas.
Para aplicar uma política, inclua a policy policy-name declaração de configuração no nível [edit protocols express-segment traffic-engineering] de hierarquia.
Nota:
O policy-name opcional. Se um nome de política não for definido, a política importa implicitamente todos os segmentos expressos para o banco de dados local de engenharia de tráfego. Um modelo de segmento expresso cria automaticamente um mapeamento um-a-um de links expressos.
Para configurar o segmento expresso, inclua a express-segment declaração de configuração no nível [edit protocols] de hierarquia.
Deixe-nos consultar Figura 1 e usar o par de LSPs RSVP-TE mostrados entre nós de borda C1 e C4 e como segmentos expressos são gerados representando os LSPs underlay. Em Figura 4, uma política é criada para representar dois LSPs RSVP-TE (ouro e ouro líquido) como um único segmento expresso.
Figura 4: Um par de LSPs RSVP-TE representados como um segmento Express
A seguir, uma política de amostra em que o nome da política é combinado com uma expressão regular e o ponto final dos LSPs 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;
}
}
Na saída de amostra a seguir, você pode ver que o segmento expresso () recém-criado (Gold-Exp-Set-192.168.1.4) juntamente com os atributos de engenharia de tráfego são herdados dos túneis RSVP-TE underlay:

Você pode observar o seguinte na saída:
-

Os atributos de engenharia de tráfego (largura de banda, métricas, grupos de administradores, SRLGs) dos RSVP-LSPs underlay são herdados pelo segmento expresso.
-
O segmento expresso é um link não numerado projetado para tráfego e foi adicionado ao banco de dados de engenharia de tráfego.
-
O rótulo 19 foi atribuído e instalado na
mpls.0tabela de encaminhamento como o SID de adjacência para o link de engenharia de tráfego virtual SR.
A seguir, um exemplo em que o destino LSP SR-TE é combinado:
protocols {

}
policy-options {

then accept;Na saída de amostra a seguir, você pode ver o segmentoset1sr-3.3.3.3 expresso () recém-criado a partir dos túneis underlay SR-TE nãocolorizados:

Como os segmentos express são anunciados?
Os segmentos express são anunciados em limites de domínio ou para controladores de nível mais alto e elementos de computação de caminho (PCEs) usando o estado do link BGP. Ao trocar informações pelo estado do link BGP, as extensões para o estado do link BGP são usadas para anunciar segmentos expressos como links projetados para tráfego. Os links projetados por tráfego por segmentos expressos e outros links normais de engenharia de tráfego aparecem no banco de dados de estado de enlace de engenharia de tráfego de qualquer LSR na rede e são usados para computação de caminhos projetados de tráfego de ponta a ponta. As entradas de banco de dados de engenharia de tráfego por segmentos express são importadas e exportadas da lsdist.0 tabela fou do anúncio através do estado do link BGP com a seguinte configuração de importação e configuração de exportação do banco de dados de engenharia de tráfego:
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 fornece uma representação visual de como os links e nós de engenharia de tráfego são espelhados entre o banco de dados de engenharia de tráfego local e o RIB que o lsdist.0 BGP-LS usa para anúncio. Como ilustrado, existem vários pontos de anexo de políticas.
Figura 5: Segmentos do Advertising Express
Como os segmentos express são usados por um elemento de computação de caminhos?
A política de exportação de estado do link BGP é um lugar eficaz para criar uma topologia abstrata ou personalizada que é anunciada a um peer projetado para tráfego. Por exemplo, você pode querer anunciar apenas o segmento expresso e os links e nós TE do Domínio 3 para PE2 de forma que a topologia projetada em tráfego seja abstraída conforme mostrado em Figura 6. A visão abstraída é então usada pelo PE2 para computação de caminhos de ponta a ponta.
Figura 6: Abstração da engenharia de tráfego domínio 2 com segmento express
A seguir, uma configuração de amostra de uma política de exportação de estado de enlace BGP no C1:
policy-options {
policy-statement abstract-topo {
from {
traffic-engineering {
protocol express-segment;
ipv4-prefix {
as 3;
}
}
}
then accept;
}
}
A seguir, uma configuração de política SR de amostra no roteador PE2 para estabelecer um caminho multi domínio de ponta a ponta 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;
}
}
}
}
}
}
O caminho de ponta a ponta resultante está representado em Figura 7. Você pode ver que o SID de adjacência do segmento express (rótulo 19) é usado na lista de segmentos SR, resultando no equilíbrio de carga do tráfego sobre os LSPs RSVP-TE de ouro líquido e ouro líquido dentro do Domínio 2.

Visão geral
A topologia a seguir (Figura 8) mostra dois domínios SR-TE (AS100 e AS300) executando a interconexão EBGP-LS por meio de um domínio RSVP-TE (AS200):
Topologia
Figura 8: Conectividade SR-TE entre domínios usando segmentos express
Nesta topologia, está estabelecido um caminho SR-TE de ponta a ponta entre o roteador PE1 e o roteador PE2. Os segmentos de engenharia por pares de saída (EPE) são definidos em roteadores PE1 e PE2 para direcionar o tráfego em direção aos nós de fronteira diretamente conectados BN1/BN2 e BN3/BN4, respectivamente. Os segmentos de EPE definidos nos nós de borda são anunciados internamente pelo estado do link BGP. Esses dois domínios SR-TE estão interconectados através do domínio (AS200) que está aproveitando os LSPs RSVP-TE para estabelecer caminhos internos.
Os nós de borda do domínio AS200 facilitam a abstração de informações SR-TE entre domínios. Os segmentos express são criados em nós de fronteira (BN1, BN2, BN3 e BN4). Os segmentos express são criados em um relacionamento único com os LSPs RSVP-TE subjacentes e todos os segmentos expressos são inseridos no banco de dados local de TE do nó de fronteira para um anúncio de estado de link BGP subsequente. O domínio AS200 utiliza underlays RSVP-TE LSP para o gerenciamento de TE e apresenta esses LSPs RSVP-TE underlay como segmentos expressos para os domínios AS100 e AS300, permitindo que os domínios tenham conectividade SR-TE LSP de ponta a ponta.

Configure o R4 (roteador BN2)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R4:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R4#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Configure o R6 (roteador BN4)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R6:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R6#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Configure o R7 (roteador PE2)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R7:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R7#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Significado
-
show express-segments detailNa saída, você pode ver o nome dos segmentos expressos (r1-exp-set1-10.6.6.6, r1-exp-set2-10.3.3.3), rótulos de segmentos expressos (25, 24) e LSPs underlay (lsp1to6_a, lsp1to3_a). -
show ted database topology-type express-segments detailNa saída, você pode ver que as entradas do segmento expresso estão inseridas no banco de dados de TE. Os segmentos expressos (links de TE virtuais) são criados dinamicamente. O protocolo usado é EXPRESS-SEG(0). -
show route table mpls.0 protocol express-segmentsNa saída, você pode ver os rótulos do segmento expresso (24,25). Como o segmento expresso é uma construção que depende dos LSPs underlay, o rótulo do segmento expresso é trocado para os rótulos LSP underlay (33,34), que é RSVP-LSP.
Verifique os anúncios do segmento Express
Propósito
Verifique se o nó de origem anuncia segmentos expressos aos vizinhos LS eBGP/iBGP.
Ação
A partir do modo operacional, execute os seguintes comandos:
-
show route table lsdist.0— Verifique se os segmentos expressos no RIB BGP-LS estão sendo anunciados. -
show route advertising-protocol bgp neighbor— Verifique se os segmentos expressos são enviados aos vizinhos LS eBGP/iBGP.

Significado
-
Na saída, o
show route table lsdist.0BGP anuncia as rotas na tabela de roteamento. A tabela de roteamento é criada a partir do banco de dados de TE. Você pode ver os links de segmentos expressos (EXPRESS-SEG/6) e os links EPE (BGP-LS-EPE:0 }/1216). -
show route advertising-protocol bgp 10.2.2.2Na saída, você pode ver o que o R1 é publicidade. Os segmentos expressos são inseridos no banco de dados te, que é copiado para RIB. O BGP-LS anuncia o RIB para o roteador peer. No peer, as informações RIB recebidas são copiadas no banco de dados local. A política neste exemplo anuncia apenas segmentos expressos e segmentos de EPE.
Verifique as informações de topologia de TE
Propósito
Verifique se os nós de entrada recebem informações de topologia de TE por meio do EBGP/iBGP LS.
Ação
A partir do modo operacional, execute os seguintes comandos:
-
show route receive-protocol bgp neighbor— Verifique se os segmentos expressos são recebidos de vizinhos LS EBGP/iBGP. -
show route table lsdist.0— Verifique se os segmentos expressos estão no BGP-LS RIB. -
show ted database topology-type l3-unicast detail— Verifique se os segmentos expressos são importados para o banco de dados TE do roteador de entrada. -
show spring-traffic-engineering lsp— Verifique se a política de SR de ponta a ponta foi computada e instalada com sucesso.

Topologia
Figura 9: Conectividade SR-TE entre domínios usando segmentos express por meio de underlay SR-TE
Nesta topologia, está estabelecido um caminho SR-TE de ponta a ponta entre o roteador PE1 e o roteador PE2. Os segmentos de engenharia por pares de saída (EPE) são definidos em roteadores PE1 e PE2 para direcionar o tráfego em direção aos nós de fronteira diretamente conectados BN1/BN2 e BN3/BN4, respectivamente. Os segmentos de EPE definidos nos nós de borda são anunciados internamente pelo estado do link BGP. Esses dois domínios SR-TE estão interconectados através do domínio (AS200) que está aproveitando os LSPs SR-TE para estabelecer caminhos internos.
Os nós de borda do domínio AS200 facilitam a abstração de informações SR-TE entre domínios. Os segmentos express são criados em nós de fronteira (BN1, BN2, BN3 e BN4). Os segmentos express são criados em uma relação única com os LSPs SR-TE subjacentes e todos os segmentos expressos são inseridos no banco de dados te local do nó de fronteira para um anúncio de estado de link BGP subsequente. O domínio AS200 utiliza underlays SR-TE LSP para o gerenciamento de TE e apresenta esses LSPs SR-TE underlay como segmentos expressos para os domínios AS100 e AS300, permitindo que os domínios tenham conectividade SR-TE LSP de ponta a ponta.

Configurar R0 (roteador PE1)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R0:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R0#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Configure o R1 (roteador BN1)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R1:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R1#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Configure o R4 (roteador BN2)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R4:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R4#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Configure o R2 (roteador intermediário)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R2:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R2#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Configure o R3 (roteador BN3)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R3:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R3#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Definir um mecanismo para criar segmentos expressos automaticamente (dinâmicos) e inseri-los no banco de dados de TE para que eles possam ser anunciados por meio do BGP-LS. Neste exemplo, segmentos expressos são criados automaticamente para todos os túneis SR underlay. Isso é feito configurando um modelo com uma política e, em seguida, segmentos expressos são criados automaticamente com base nas políticas.

Configure o R6 (roteador BN4)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R6:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R6#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Definir um mecanismo para criar segmentos expressos automaticamente (dinâmicos) e inseri-los no banco de dados de TE para que eles possam ser anunciados por meio do BGP-LS. Neste exemplo, segmentos expressos são criados automaticamente para todos os túneis SR underlay. Isso é feito configurando um modelo com uma política e, em seguida, segmentos expressos são criados automaticamente com base nas políticas.

Configure o R7 (roteador PE2)
Procedimento passo a passo
O exemplo a seguir exige que você navegue por vários níveis na hierarquia de configuração. Para obter informações sobre como navegar na CLI, consulte Usando o Editor de CLI no modo de configuração no Guia do usuário da CLI.
Para configurar o dispositivo R7:
-
Configure o modo de serviços de rede como IP aprimorado. O IP aprimorado define os serviços de rede do roteador para um protocolo de Internet aprimorado e usa recursos aprimorados de modo.
[edit] user@R7#set chassis network-services enhanced-ip
Depois de configurar a
enhanced-ipdeclaração e confirmar a configuração, a seguinte mensagem de aviso aparece solicitando que você reinicialize o roteador:'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
A reinicialização traz os FPCs no roteador.
-
Configure as interfaces para habilitar o transporte IP, MPLS e ISO.

Verificação
Para confirmar que a configuração está funcionando corretamente, execute as seguintes tarefas:
- Verifique o segmento Express
- Verifique os anúncios do segmento Express
- Verifique as informações de topologia de TE
Verifique o segmento Express
Propósito
Verifique se os segmentos expressos foram criados corretamente.
Ação
A partir do modo operacional, execute os seguintes comandos:
-
show express-segments detail— Verifique se os segmentos expressos são criados. -
show ted database topology-type express-segments detail— Verifique se os segmentos expressos recém-criados estão inseridos no banco de dados de TE. -
show route table mpls.0 protocol express-segments— Verifique se as entradas de encaminhamento foram criadas.

-
show express-segments detailNa saída, você pode ver o nome do segmento expresso (set1sr-10.3.3.3), rótulo de segmento expresso (16) e LSP (lsp1to3_srunderlay). -
show ted database topology-type express-segments detailNa saída, você pode ver que as entradas do segmento expresso estão inseridas no banco de dados de TE. Os segmentos expressos (links de TE virtuais) são criados dinamicamente. O protocolo usado é EXPRESS-SEG(0). -
show route table mpls.0 protocol express-segmentsNa saída, você pode ver o rótulo do segmento expresso (16). Como o segmento expresso é uma construção que depende dos LSPs underlay, o rótulo do segmento expresso é trocado para os rótulos SR-TE underlay (801003).
Verifique os anúncios do segmento Express
Propósito
Verifique se o nó de origem anuncia segmentos expressos aos vizinhos LS eBGP/iBGP.
Ação
A partir do modo operacional, execute os seguintes comandos:
-
show route table lsdist.0— Verifique se os segmentos expressos no RIB BGP-LS estão sendo anunciados. -
show route advertising-protocol bgp neighbor— Verifique se os segmentos expressos são enviados aos vizinhos LS eBGP/iBGP.

Significado
-
Na saída, o
show route table lsdist.0BGP anuncia as rotas na tabela de roteamento. A tabela de roteamento é criada a partir do banco de dados de TE. Você pode ver os links de segmentos expressos (EXPRESS-SEG/6) e os links EPE (BGP-LS-EPE:0 }/1216). -
show route advertising-protocol bgp 10.2.2.2Na saída, você pode ver o que o R1 é publicidade. Os segmentos expressos são inseridos no banco de dados te, que é copiado para RIB. O BGP-LS anuncia o RIB para o roteador peer. No peer, as informações RIB recebidas são copiadas no banco de dados local. A política neste exemplo anuncia apenas segmentos expressos e segmentos de EPE.
Verifique as informações de topologia de TE
Propósito
Verifique se os nós de entrada recebem informações de topologia de TE por meio do EBGP/iBGP LS.
Ação
A partir do modo operacional, execute os seguintes comandos:
-
show route receive-protocol bgp neighbor— Verifique se os segmentos expressos são recebidos de vizinhos LS EBGP/iBGP. -
show route table lsdist.0— Verifique se os segmentos expressos estão no BGP-LS RIB. -
show ted database topology-type l3-unicast detail— Verifique se os segmentos expressos são importados para o banco de dados TE do roteador de entrada. -
show spring-traffic-engineering lsp— Verifique se a política de SR de ponta a ponta foi computada e instalada com sucesso.

Significado
-
show route receive-protocol bgp 192.168.1.2Na saída, ela mostra as rotas que foram recebidas pelo roteador de entrada (R0) do vizinho BGP, que descreve o segmento express (links de TE virtuais). -
show route table lsdist.0Na saída, ela mostra as rotas que foram recebidas pelo roteador de entrada (R0) e se elas estão inseridas na lsdist.0 RIB. Ele também mostra se o lsdist.0 RIB é copiado no banco de dados te local. -
show ted database topology-type l3-unicast detailNa saída, as rotas são copiadas no banco de dados local de TE. Este set1sr-10.3.3.3 é um segmento expresso com ponto final como 3,3,3,3 e é criado com sucesso na R1. A R1 anunciou o segmento expresso e o R0 o inseriu no banco de dados local de TE. Você também pode ver os segmentos de EPE (epe_adj1_toR7). -
show spring-traffic-engineering lspNa saída, você pode ver que as políticas SR estão ativas. Isso mostra que agora você é capaz de computar uma política SR de ponta a ponta multi domínio (R0 a R7). -
show spring-traffic-engineering lsp detailNa saída, você pode ver as etiquetas selecionadas. computelsp1 No LSP, o rótulo 7101 é um segmento de EPE, 16 é o segmento expresso, e 7137 também é um segmento de EPE. Isso mostra que agora você é capaz de computar uma política SR de ponta a ponta multi domínio (R0 a R7).
