MPLS Vrf opsf interfaces not working

P/PE router VRF ospf interfaces unable to receive or advertised routing to and from CE router.

Config attahced.

Routes from PE VRF nortel shld be forwarded to CE router

So are routes from CE network

Any ideas?


Re: MPLS Vrf opsf interfaces not working


Looks to me as if you did not start the ospf process in the VRF. So adjust the config according to:

interface Serial2/0

description MPLS VRF 1:1 connection to Cisco 2611 PPP

ip vrf forwarding nortel

ip address

encapsulation ppp

clock rate 128000

interface FastEthernet4/0

description MPLS connection for vrf Nortel 1:1

ip vrf forwarding nortel

ip address

duplex auto

speed auto

no router ospf 1

router ospf 1 vrf nortel

network area 0

network area 0 !In case you want OSPF over this interface as well

With the current config I would assume that you do not see an OSPF adjacency on the CE.

Hope this helps! Please rate all posts.

Re: MPLS Vrf opsf interfaces not working

Hi Martin,

using OSPF VRF process has resolved the problem of loosing ospf adjacency, once applied "ip vrf forwarding".

Now, I am getting new problem, Lo0 of the PEs are no longer reachable, regradless the fact OSPF ajacency is established between the P-router to PE-routers and Lo0s are advertised by OSPF VRF process.

Please advise.

The PEs loopback interface should not belong to any particular VRF but to the global routing table. Can you please post your updated configurations.
