Configuración de fugas de VRF en IOS XE

Introducción

Este documento describe y proporciona configuraciones de ejemplo para los métodos comunes de ruteo y reenvío virtual (VRF) de fuga de ruta.

Prerequisites

Requirements

Cisco recomienda que tenga conocimiento sobre estos temas:

• Border Gateway Protocol (BGP)
• Redistribución del protocolo de ruteo
• VRF
• Software Cisco IOS® XE

Para obtener más información sobre estos temas, consulte:

Redistribución de protocolos de routing

Ejemplo de Configuración de Redistribución Mutua entre EIGRP y BGP

Comprensión de la Redistribución de Rutas OSPF en BGP

Componentes Utilizados

La información de este documento se basa en los routers con las versiones 16.12.X y 17.X de Cisco IOS® XE

La información que contiene este documento se creó a partir de los dispositivos en un ambiente de laboratorio específico. Todos los dispositivos que se utilizan en este documento se pusieron en funcionamiento con una configuración verificada (predeterminada). Si tiene una red en vivo, asegúrese de entender el posible impacto de cualquier comando.

Antecedentes

VRF permite que un router mantenga tablas de ruteo separadas para diferentes redes virtuales. Cuando se necesitan excepciones, la fuga de ruta VRF permite que parte del tráfico se rutee entre los VRF sin el uso de rutas estáticas.

Escenario 1 - Fuga de ruta VRF entre BGP e IGP ( EIGRP )

El escenario 1 proporciona un ejemplo de fuga de ruta VRF entre BGP y EIGRP. Este método se puede utilizar para otros IGP.

Diagrama de la red

El diagrama de red que se muestra en la imagen 1 muestra la topología de capa 3 en la que es necesaria la fuga de rutas.


Imagen 1. Topología de fuga de ruta para el escenario 1

El router "LEAK" tiene una vecindad BGP con un vecino en VRF A y un vecino EIGRP en el VRF global.  El dispositivo 192.168.11.11 debe poder conectarse al dispositivo 172.16.10.10 a través de la red.

El Router LEAK no puede rutear entre los dos ya que las rutas están en VRFs diferentes.  Estas tablas de ruteo muestran las rutas actuales por VRF e indican qué rutas deben filtrarse entre el VRF global y el VRF A.

Configurar

Realice los procedimientos para crear la fuga entre las dos tablas de ruteo:

Step 1.
Create route-maps to filter the routes to be injected in both routing tables.

LEAK(config)#Route-map VRF_TO_EIGRP
LEAK(config-route-map)#match ip address prefix-list VRF_TO_EIGRP
LEAK(config-route-map)#exit
!
Prefix-list created to match the host that is attached to the previous route-map configured.
!
ip prefix-list VRF_TO_EIGRP permit 172.16.10.10/32

or

LEAK(config)#Route-map VRF_TO_EIGRP
LEAK(config-route-map)# match ip address 10 
LEAK(config-route-map)#exit
!
ACL created to match the host that is attached to the previous route-map.
!
LEAK#show ip access-lists 10 
10 permit 172.16.10.10

LEAK(config)#Route-map EIGRP_TO_VRF
LEAK(config-route-map)#match ip address prefix-list EIGRP_TO_VRF 
LEAK(config-route-map)#exit
LEAK(config)#
!
Prefix-list created to match the host that is attached to the previous route-map configured.
!
ip  prefix-list EIGRP_TO_VRF  permit 192.168.11.11/32

or

LEAK(config)#Route-map EIGRP_TO_VRF
LEAK(config-route-map)#match ip address 20 
LEAK(config-route-map)#exit
LEAK(config)#
!
ACL created to match the host that is attached to the previous route-map.
!
LEAK#show ip access-list 20
10 permit 192.168.11.11


Step 2.
Define the import/export maps and add the route-map names.

LEAK(config)#vrf definition A 
LEAK(config-vrf)#address-family ipv4 
LEAK(config-vrf-af)#import ipv4 unicast map EIGRP_TO_VRF >> Import the global routing table routes at the VRF routing table.
LEAK(config-vrf-af)#export ipv4 unicast map VRF_TO_EIGRP >> Export the VRF routes to the Global Routing Table.
LEAK(config-vrf-af)#end

Step 3. 
Proceed with the dual redistribution.

Redistribute EIGRP 

LEAK(config)#router bgp 1
LEAK(config-router)#redistribute eigrp 1 
LEAK(config-router)#end

Redistribution BGP

LEAK(config)#router eigrp 1
LEAK(config-router)#redistribute bgp 1 metric 100 1 255 1 1500 
LEAK(config-router)#end

Configurar

Realice estos procedimientos para crear la fuga entre las dos tablas de ruteo:

Step 1.
Create route-maps to filter the routes to be injected in both routing tables.

LEAK(config)#Route-map VRFA_TO_VRFB 
LEAK(config-route-map)#match ip address prefix-list VRFA_TO_VRFB 
LEAK(config-route-map)#exit
!
Prefix-list created to match the host and IP segment that is attached to the previous route-map configured.
!
ip prefix-list VRFA_TO_VRFB permit 172.16.10.10/32
ip prefix-list VRFA_TO_VRFB permit 10.0.0.0/30

or

LEAK(config)#Route-map VRFA_TO_VRFB 
LEAK(config-route-map)#match ip address 10 
LEAK(config-route-map)#exit
!
ACL created to match the host and IP segment that is attached to the previous route-map.
!
LEAK#show ip access-lists 10

LEAK(config)#Route-map VRFB_TO_VRFA 
LEAK(config-route-map)#match ip address prefix-list VRFB_TO_VRFA

!
LEAK#show ip access-lists 20 
10 permit 192.168.11.11
20 permit 192.168.1.0

Step 2.
At the VRFs configure the import/export map, use the route-map names to leak the routes.

LEAK(config)#vrf definition A 
LEAK(config-vrf)#address-family ipv4 
LEAK(config-vrf-af)#export map VRFA_TO_VRFB

LEAK(config-vrf)#address-family ipv4 
LEAK(config-vrf-af)#export map VRFB_TO_VRFA 
LEAK(config-vrf-af)#import map VRFA_TO_VRFB 

Step 3.
Add the route-target to import and export the route distinguiser from both VRFs.

! --- Current configuration for VRF A

vrf definition A

!

route-target export 1:2 
route-target import 1:1

! --- Import routes from VRF A to VRF B and export routes from VRF B

LEAK(config-vrf-af)#vrf definition B

Configurar

Realice estos procedimientos para crear la fuga entre las dos tablas de ruteo:

Step 1.
Create route-maps for import and export to be injected in both routing tables.

LEAK(config-route-map)#match ip address prefix-list OSPF_TO_EIGRP 
LEAK(config-route-map)#exit

!
LEAK#show ip access-lists 20

Step 2.
Add the import/export maps in order to match the route-map names.

LEAK(config-vrf-af)#import ipv4 unicast map EIGRP_TO_OSPF
LEAK(config-vrf-af)#export ipv4 unicast map OSPF_TO_EIGRP

Step 3.
To perform the leak is necessary to create a BGP process, in order to redistribute 
the IGPs protocols.

router bgp 1
bgp log-neighbor-changes
! 
address-family ipv4 vrf B >> Include the address-family to inject VRF B routing table (OSPF)
!
exit-address-family

Nota: Asegúrese de que el VRF tenga un Distinguidor de Ruta configurado para evitar el error:
"%vrf B does not have "rd" configured, please configure "rd" before configuring import route-map"

Step 4.
Create a Dual Redistribution.

IGPs redistribution.
