Hello,
Please can someone help me with vrf lite with ospf. I am trying to ping IP's using vrf lite and SVI's. The devices are connected via trunk ports. This configuration works fine when using regular ospf. But for some reason (obviously misconfiguration) I am not seeing the routes from the peers.
switch1#sh run int te2/8
Building configuration...
Current configuration : 241 bytes
!
interface TenGigabitEthernet2/8
description Link to switch2
switchport mode trunk
end
router ospf 1 vrf red
network 172.16.10.0 0.0.0.255 area 0
!
cr01.srv-mk#sh run | b ip vrf red
ip vrf red
description ## Red VRF ##
!
switch1#sh run int vl10
Building configuration...
Current configuration : 85 bytes
!
interface Vlan10
ip vrf forwarding red
ip address 172.16.10.1 255.255.255.0
end
switch1#sh ip ospf neighbor
Neighbor ID Pri State Dead Time Address Interface
172.16.1.2 1 FULL/DR 00:00:33 172.16.10.2 Vlan10
cr01.srv-mk#sh ip route vrf red
Routing Table: red

a - application route

Gateway of last resort is not set

end
any help would be greatly appreciated.

Hi,
I am not sure if it will help but try configuring the capability vrf-lite command in the OSPF process 1 on all routers where OSPF 1 runs in a VRF.
I assume you are not runing MPLS L3VPN, are you?
Best regards,
Peter

Hello,
Thanks for the suggestion, the problem was I needed to create an SVI's for each vrf's with ip address block shared by all routes in order to build adjacency.
