Este dia les traigo a ustedes un ejercicio de mucho interés para los Service Providers, actualmente muchos SP cuentan con sus redes MPLS funcionando en la cual proveen servicios de VPNv4 sobre MPLS también llamadas MPLS VRF, en esta oportunidad les presentare el servicio de VPNv6 con el cual un SP puede proveer transporte de prefijos IPv6 a través de una red MPLS nativa de IPv4, esta tecnología es llamada 6VPE el cual es un mecanismo de despliegue de IPv6, ya que no es necesario modificar la red interna MPLS del SP, únicamente es necesario activar el address-family VPNv6 de MBGP, para hacer mas interesante el diseño de esta oportunidad implementaremos dos CPE los cuales serán los clientes de IPv6, sin embargo haremos que estos clientes funcionen dual stack es decir que puedan enviar tanto trafico en v4 como en v6, ademas implementaremos un Route Reflector en el Core MPLS, recordemos que Route Reflector es una solución que permite alta escalabilidad en cuanto al manejo de sesiones BGP dentro de un Service Provider.
Definiendo algunas bases:
El protocolo de intercambio de loopbacks será OSPF
El Route Reflector será el equipo 10.0.0.5
Los PE serán 10.0.0.1 y 10.0.0.3
Los equipos P unicamente haran swap de labels MPLS por lo que no tendrán configuración de BGP.
Los CPE no correrán ningún protocolo de enrutamiento por lo que simplemente tendrán rutas por defecto apuntando hacia su interfaz principal.
Partiremos de la siguiente topología:
En dicha topologia ya contamos con un IGP y LDP corriendo en la red lo comprobamos en los equipos PE, los archivos de configuración para establecer esta conectividad se encuentran al final de este post:

A continuación mostramos la configuración en ambos CPE:
CPE1:

!

!
!
En los PE recibiremos estas conexiones directamente en una VRF que llamaremos 6VPE, para crear esta VRF lo haremos de forma diferente a una VRF VPNv4 convencional a continuación se presenta la configuración necesaria en PE1, la misma configuración de la VRF aplica para PE2
PE1:
vrf definition 6VPE
rd 1:100
!

route-target export 1:100
route-target import 1:100
exit-address-family
!

duplex full
ipv6 address 2001:192:168:1::1/64
ipv6 address autoconfig
end
El valor de RD 1:100 lo elegimos de forma arbitraria, una red de SP utilizan RD definidos bajo reglas haciendo relación a números de sistemas autónomos y parámetros especiales de cada equipo.
Es importante notar que definimos dos Address-Family dentro de esta VRF, por lo que será una VRF dual stack en la cual tendremos dos tablas de enrutamiento una para v4 y otra para v6.
Configuramos PE1 y PE2 para hablar MPBGP con el Route Reflector en dos diferentes Address-Family VPNv4 y VPNv6
PE1:
router bgp 1
bgp router-id 10.0.0.1
no bgp default ipv4-unicast
bgp log-neighbor-changes
neighbor 10.0.0.5 remote-as 1
neighbor 10.0.0.5 update-source Loopback0
!
address-family ipv4
no synchronization
no auto-summary
exit-address-family
!
address-family vpnv4
neighbor 10.0.0.5 activate
neighbor 10.0.0.5 send-community both
exit-address-family
!
address-family vpnv6
neighbor 10.0.0.5 activate
neighbor 10.0.0.5 send-community both
exit-address-family
!
Adicionalmente definimos dos address-family para la VRF 6VPE estos serán IPv4 e IPv6, con los siguientes comandos indicamos a BGP que deberá redistribuir las rutas conectadas en la VRF 6VPE tanto IPv4 como IPv6:
PE1:
router bgp 1
address-family ipv4 vrf 6VPE
no synchronization
redistribute connected
exit-address-family
!
address-family ipv6 vrf 6VPE
redistribute connected
no synchronization
exit-address-family
!
!
Con respecto al Route Reflector es de importancia revisar la configuración de BGP en el cual podemos apreciar la instrucción donde definimos que los equipos 10.0.0.1 y 10.0.0.3 son clientes de Route Reflector
RR:
router bgp 1
no bgp default ipv4-unicast
bgp log-neighbor-changes
neighbor 10.0.0.1 remote-as 1
neighbor 10.0.0.1 update-source Loopback0
neighbor 10.0.0.3 remote-as 1
neighbor 10.0.0.3 update-source Loopback0
!
address-family ipv4
no synchronization
no auto-summary
exit-address-family
!
address-family vpnv4
neighbor 10.0.0.1 activate
neighbor 10.0.0.1 send-community both
neighbor 10.0.0.1 route-reflector-client
neighbor 10.0.0.3 activate
neighbor 10.0.0.3 send-community both
neighbor 10.0.0.3 route-reflector-client
exit-address-family
!
address-family vpnv6

neighbor 10.0.0.1 route-reflector-client
neighbor 10.0.0.3 activate
neighbor 10.0.0.3 send-community both
neighbor 10.0.0.3 route-reflector-client
exit-address-family

Comprobamos las sesiones BGP VPNv4 en el Route Reflector

Podemos ver que cada PE nos esta enviando 1 prefijo tanto para la VPNv4 como para la VPNv6, estos prefijos son las rutas directamente conectadas hacia los CPE.
En PE1 podremos ver en cada tabla de enrutamiento que tenemos aprendido por BGP el prefijo de PE2 y vice versa
A continuación se presentan las tablas de enrutamiento para PE1:
PE1:
