Re: Not able to ping loopback interface

Hi,

You should have VRF aware OSPF configured. Take a look at your example
and check if you have OSPF neighbor relationship established. I bet
you don't.

R2:
no router ospf 1
router ospf 1 vrf R2_VRF_24
 network 150.1.24.2 0.0.0.0 area 0
 network 150.1.124.2 0.0.0.0 area 0
router ospf 2 vrf R2_VRF_42
 network 150.1.42.2 0.0.0.0 area 0
 network 150.1.142.2 0.0.0.0 area 0

R4:
no router ospf 1
router ospf 1 vrf R4_VRF_24
 network 150.1.24.4 0.0.0.0 area 0
 network 150.1.124.4 0.0.0.0 area 0
router ospf 2 vrf R4_VRF_42
 network 150.1.42.4 0.0.0.0 area 0
 network 150.1.142.4 0.0.0.0 area 0

HTH,
