Hi,
I am running MPLS VPN with RIP and OSPF at CE ends.
* OSPF for R3 - R1(ospf process 3) and R4 - R5 (ospf process 4)
* RIP for R4 - R6
I am using two vrfs CA( for R3-R1 and R4-R5) and CB (for R4-R6).
for R1 at R3
ip vrf CA
rd 1:10
route-target export 1:105
route-target export 1:615 // used for R6 to communicate with R1 and R5 for some reasons
route-target import 1:105
route-target import 1:615 // used for R6 to communicate with R1 and R5 for some reasons
for R5 at R4
ip vrf CA
rd 1:50
route-target export 1:105
route-target export 1:615
route-target import 1:105
route-target import 1:615
for R6 at R4
ip vrf CB
rd 1:60
route-target export 1:600
route-target export 1:615
route-target import 1:600
route-target import 1:615
Now for Communicating R6 with R1 and R5 ( for some reasons) i am using RT 1:615 both (other wise not needed as previously i was using RT 1:600 only and there was no vrf CB at R3 so to get CA routes into CB i used 1:615 for R6).
My Problem is :- I am not able to ping R5's loopback ip from R6 as i am not getting the route for 5.5.5.5 (R5's loopback). But i am able to ping the serial link ip address of R5.
from R6 to R1 ping is successful
from R6 to R1 ping is successful
from R1 to R5 ping is successful
from R5 to R1 ping is successful
from R5 to R6 ping is successful
from R6 to R5 ping is unsuccessful ( i am not getting route for R5's loopback). But i am able to ping the serial link ip address of R5.
Kindly help
