I had a non-backbone/non-stub area, with loopback address 192.168.253.27. the redistributed connected subnets does not include the VLAN1 network, but include the lo0. sh int vlan 1 showed that vlan 1 is up, line protocol is up. There should be a Route Link State and Type-5 AS External Link States for the vlan 1 as the lo0.Why the VLAN 1 network is not even in the ospf database? Any help is appreciated.

I had FWSM in the test switch. It's using VLAN 1 when booted into the maintenance partition. I am not sure whether this has anything to do with the vlan 1 redistribution.
