vrf lite not working with vlan interfaces

choudhury.amd1

Level 1

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

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

cr01.srv-mk#sh ip route vrf red

Gateway of last resort is not set

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.

regards
