I have iBGP peering using loopback address ( 172.16.1.1 router A and 172.16.1.2 router B) between two routers
and ospf is configured in the internal segment and redistributed to ospf and manipulated the the metrics
for the best path selection . MED is configured ,so all the lan traffic will always take 172.16.1.1 for communicating the MPLS cloud
( I have four networks 172.16.0.0 ,172.17.0.0,10.0.0.0 and 184.108.40.206). If Router A lan segment failed users will be able to reach via RouterB to 172.17.84.X (Mpls cloud)
But in this case this is not happening properly .
1. If i shutdown the Loopback interface of RouterA i can able to reach 172.17.84.X. via RouterB
2. If a user in the 172.17 .X.X segment is not able to reach 172.17.84.x via RouterB
Kindly help me to findout a workaround solution for the above mentioned issue .
