Inter vrf ping on same router

[NVBangera]

I have configured two vrf LI and OAM  on a 7609 router. and inter vrf routing is enabled. I am able to see corresponding routes in either vrf.

Basically two connected routes from OAM vrf are leaked into LI vrf and vice versa. The following output is seen on across LI vrf for interface routes of OAM vrf.

OKH-MAX_R1#show ip cef vrf LI 10.181.172.194 detail

10.181.172.194/32, epoch 6, flags receive

  Interface source: Vlan234

  receive for Vlan234

OKH-MAX_R1#show ip cef vrf LI 10.181.172.130 detail

10.181.172.130/32, epoch 6, flags receive

Dependent covered prefix type cover need deagg cover 10.181.172.128/26

  Interface source: Vlan210

  receive for Vlan210

Vlan 234 and Vlan 210 are part of OAM vrf. I am able to ping 10.181.172.194 from LI vrf but not able to ping 10.181.172.130. The only difference between the two output is highlighted above. Does this output has anything to do with the issue.

Can you post the configs for all 3 vrfs and vlans?
