[c-nsp] 3550 VRF-Lite and OSPF

    I am trying to set-up Cat 3550 to be in NSSA area in separate VRF 
connected to 7200's main routing table and I seem to have some problems that 
I don't quite understand.

    If I configure global routing table OSPF on 3550, everything works like 
a charm (I get all the LSA's, they are all in the routing table). However, 
with VRF-lite, I know that OSPF is getting all the LSA's, but none of them 
are inserted into the routing table for the VRF:

Switch#sh ip ospf database

            OSPF Router with ID (xxx.xxx.xxx.170) (Process ID 10)

                Router Link States (Area 354354)

-----
Gateway of last resort is not set

     xxx.xxx.xxx.0/30 is subnetted, 1 subnets
C       xxx.xxx.xxx.168 is directly connected, FastEthernet0/1

    Below is the relevant config:

ip vrf TEST
 rd 11:11
 route-target export 11:11
 route-target import 11:11
!
interface FastEthernet0/1
 no switchport
 ip vrf forwarding TEST
 ip address xxx.xxx.xxx.170 255.255.255.252
 ip ospf mtu-ignore
!
router ospf 10 vrf TEST
 log-adjacency-changes
 area 354354 nssa
 network xxx.xxx.xxx.168 0.0.0.3 area 354354
!

 The current template is the default extended-match template.
 The selected template optimizes the resources in
 the switch to support this level of features for
 8 routed interfaces and 1K VLANs.

 number of unicast mac addresses:   5K
 number of igmp groups:             1K
 number of qos aces:                1K
 number of security aces:           1K
 number of unicast routes:          4K
 number of multicast routes:        1K


    Any ideas?


Kind regards,
Marko.
