Dear rajivmahuli1982,

yes, but you must use the

import functionality of route-target and enable Border Gateway Protocol (BGP) on the router, This solution documented by Cisco in the below URL.

http://www.cisco.com/en/US/tech/tk436/tk832/technologies_configuration_example09186a0080231a3e.shtml

There is some changes in the below example as this is my self test for this document.

ip vrf VRF-A

rd 1:1

route-target export 1:1

route-target import 1:1

route-target import 2:1

!

ip vrf VRF-B

rd 2:1

route-target export 2:1

route-target import 2:1

route-target import 1:1

!

interface Serial1/0

ip vrf forwarding VRF-A

ip address 192.168.99.1 255.255.255.0

!

interface Serial1/1

ip vrf forwarding VRF-B

ip address 172.16.10.1 255.255.255.0

router bgp 1

!

address-family ipv4 vrf VRF-A

redistribute connected

!

address-family ipv4 vrf VRF-B

redistribute connected

Hi Mounir,

thanks for the reply but what if there is no MPBGP peering at all if its a standalone router will this still work ??

yes even if no BGP neighbor configured.

Please rate helpful posts.
