It's a good idea to explain what your network diagram is. Did you configure any Virtual-link as well?

Could you post a diagram showing which router it should be learning this route from and where the network originates etc. If you could also show your running config for OSPF on both routers that may be helpful.

Hello Mahesh,

this kind of problem can happen for a mismatch in OSPF network type at the two ends of the link.

Check with sh ip ospf interface typex/y

on both devices

another possible issue is overlapping OSPF Router-IDs

I agree with Mike and Toshi that more details are needed to provide help

Hope to help

Topology is

CPE1--PE1--mpls coud--PE2-CPE2

CPE2 originates a route which is not there in routing table of CPE1 but there in database.

Moreover at PE2 and CPE2 network type is point-to-point

if any more details required please let me know

Hello Mahesh,

Are you using VRFs on the CPE1? If yes then, first, you have to verify the presence of the route in the respective VRF. Your "show ip route" verified only the global routing table.

Further on, it is possible that the network is removed by additional checks in OSPF against routing loops. These checks are not suitable if a customer uses VRFs himself. You can try turning them off in the respective OSPF process configuration using this command:

capability vrf-lite

Best regards,
