Ejemplo: Configuración de comunidades en una directiva de enrutamiento
Una comunidad es un atributo de ruta utilizado por BGP para agrupar administrativamente rutas con propiedades similares.
Requisitos
No se necesita ninguna configuración especial más allá de la inicialización del dispositivo antes de configurar este ejemplo.
- Actualizado y revalidado con vMX en Junos OS versión 21.1R1.
Descripción general
Una función principal del atributo community es ser un valor de etiqueta administrativa que se utiliza para asociar rutas. Generalmente, estas rutas comparten algunas propiedades comunes, pero eso no es obligatorio. Las comunidades son una herramienta flexible dentro de BGP. Se puede asignar un valor de comunidad individual a una sola ruta o a varias rutas. A una ruta se le puede asignar un único valor de comunidad o varios valores. Las redes utilizan el atributo community para ayudar en la implementación de directivas de enrutamiento administrativo. El valor asignado de una ruta puede permitir que sea aceptada en la red, o rechazada de la red, o permitir que modifique atributos.
Figura 1 muestra los dispositivos R1, R2 y R3 como pares BGP internos (IBGP) en el sistema autónomo (AS) 64510. El dispositivo R4 anuncia el espacio de direcciones 172.16.0.0/21 del AS 64511.
Topología
Las rutas específicas que recibe el dispositivo R1 desde el dispositivo R4 son las siguientes:
user@R1> show route receive-protocol bgp 10.0.0.13
inet.0: 24 destinations, 28 routes (24 active, 0 holddown, 0 hidden)
Prefix Nexthop MED Lclpref AS path

* 172.16.1.0/24 10.0.0.13 64511 I
* 172.16.2.0/24 10.0.0.13 64511 I
* 172.16.3.0/24 10.0.0.13 64511 I

172.16.5.0/24 10.0.0.13 64511 I
172.16.6.0/24 10.0.0.13 64511 I
172.16.7.0/24 10.0.0.13 64511 I
Los administradores del AS 64511 desean recibir cierto tráfico de usuarios del dispositivo R1 y otro tráfico de usuarios del dispositivo R3. Para lograr este objetivo administrativo, el dispositivo R4 asocia el valor de comunidad de 64511:1 a algunas rutas que envía y asocia el valor de comunidad 64511:3 a otras rutas que envía. Las directivas de enrutamiento del AS 64510 se configuran mediante un criterio de coincidencia de comunidad para cambiar la preferencia local de las rutas recibidas a nuevos valores que alteran el algoritmo de selección de ruta del BGP. Se prefiere la ruta con el valor de preferencia local más alto.
En el dispositivo R1, a las rutas con el valor de comunidad 64511:1 se les asigna una preferencia local de 200 y a las rutas con el valor de comunidad 64511:3 se les asigna una preferencia local de 50. En el dispositivo R3, se realiza lo contrario para que a las rutas con el valor de comunidad 64511:3 se les asigne una preferencia local de 200 y a las rutas con el valor de comunidad 64511:1 se les asigne una preferencia local de 50. Esta información es comunicada a través del IBGP tanto por el dispositivo R1 como por el dispositivo R3 al dispositivo R2.
