i have 2 core routers that is connected via MPLS tunnelling.
I setup a new vlan in one of the layer 3 switch at router A,
10.200.100.0/24, there is one existing vlan at 10.200.90.0/24.
router A -> router B
under the ospf routing, there is this area 0 to exchange the LAN segments through the ospf area 1.
do I have to change the wildcard mask in order for the 2nd vlan to go theough ?
router ospf 1
log-adjacency-changes
area 0 authentication message-digest
area 1 authentication message-digest
area 1 range 10.200.0.0 255.255.128.0
area 1 range 10.205.1.0 255.255.255.192
routerA#sh ip route | i 10.200.100
S 10.200.100.0/24 [1/0] via 10.200.90.4
routerA#sh ip route | i 10.200.90
C 10.200.90.0/24 is directly connected, GigabitEthernet0/0
S 10.200.100.0/24 [1/0] via 10.200.90.4
routerB1#sh ip route | i 10.200.100
routerB#sh ip route | i 10.200.90
O 10.200.90.0/24 [19/1001] via 10.205.5.254, 1d00h, Tunnel1090

Your configuration looks a bit strange. You have no network statements. Do you have OSPF enabled on the interface instead with the ip ospf interface command?
Can you post show ip ospf interface brief?
It looks like you have a static route for 10.200.100.0 and then area statement under OSPF. OSPF will not summarize route unless it is in the OSPF RIB.
To just advertise the network you should put a network statement or enable OSPF on the interface with the ip ospf area command.

how do i change the ospf to enable 10.200.100.0/24 instead of static route
02-05-2014 03:18 AM
It's not clear what you are asking.
Is the new network 10.200.100.0/24 a common network between router 1 and router 2 ie. both routers have an interface in that network.
Or does the network only connect to the one router ? If so which one.
How is this related to the static statement ?
