Communication between VRF on same PE routers

[lambay2000]

Hello,

A---------PE-1--------P----------PE-2

Am connecting to different customers on same PE and they want to communicate with each other,after importing route-target the next-hop for customer-A routes from Customer-B, is the interface associated with customer-A VRF on the PE-1 router,Customer-B is not able to ping the interface of customer-A,Because here they are not receiving a MBGP update the next-hop is the connected interface of another VRF. To make them reacheable what i have do????

Solution:

Pointing static VRF routes to global routing table of PE-2  and in global routing table of PE-1 pointing global static route to networks of CUSt-A with  particular next-hop of associated VRF interface and redistribute the global static routes in dynamic routing protocol then only PE-2 will come to know where the routes are located for customer-A.By doiing this the traffic flow for connected customer is through PE-2.

Any alternate solution guys

Thanks

Hello Lambay2000,

>> Because here they are not receiving a MBGP update the next-hop is the connected interface of another VRF. To make them reacheable what i have do????

you need to redistribute connected in address-family ipv4 vrf VRFA

router bgp xx

address-family ipv4 vrf VRFA

redistribute connected

also you need on each VRF to import the route-target used for export in the other VRF

ip vrf VRFA

rd  100:101

route-target import 100:200

route-target import 100:100

route-target export 100:100

ip vrf VRFB

rd  100:102

route-target import 100:200

route-target import 100:100

route-target export 100:200

Hope to help
