I use a Cisco 7200 with OSPF running on a VRF interface. I have problems with OSPF when I upgrade the router from ISO 12.2.(2)T to 12.2(4)T or 12.2(7)T. After the upgrade all interfaces that belong to a VRF instance still stay in passive mode (no OSPF hello).
Anyone experiment the same problem?
IOS bug or wrong configuration?
rtr# sh running-config | begin router
router ospf 50 vrf ips0
auto-cost reference-bandwidth 10000
area 5001 authentication message-digest
network 172.26.1.0 0.0.0.255 area 5001

rtr# sh ip ospf 50 interface

I found the problem. If an OSPF process has a "passive-interface default" definition, it affects all OSPF process. In my case the "passive-interface default" was configure on OSPF process that was running on the global router and it affects all other OSPF process that was running on VRF instance.
