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.

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.
