Lets make it simple..
R1 :
router ospf 300 vrf GIT
router-id 192.168.1.17
log-adjacency-changes
redistribute static metric-type 1 subnets
network 10.10.10.0 0.0.0.3 area 5
network 172.22.80.180 0.0.0.3 area 0
network 192.168.1.17 0.0.0.0 area 0
network 202.63.64.0 0.0.15.255 area 0
network 202.130.192.0 0.0.31.255 area 0
network 203.89.96.0 0.0.31.255 area 0
R2 :
router ospf 300 vrf GIT
log-adjacency-changes
network 10.10.10.0 0.0.0.3 area 5
!
R2#sh ip route vrf GIT ospf
Routing Table: GIT
203.89.100.0/29 is subnetted, 1 subnets
O E1 203.89.100.80 [110/21] via 10.10.10.1, 00:12:51, FastEthernet0/1
O E1 202.130.198.0/24 [110/21] via 10.10.10.1, 00:12:51, FastEthernet0/1
Where are the other routes missing :(
