VRF-Lite OSPF

Hello,

I have two VRFs: global and local.

R2#sh ip route vrf global | begin Gateway

Gateway of last resort is not set

100.0.0.0/24 is subnetted, 1 subnets

B 100.100.100.0 [20/0] via 20.0.0.2, 00:50:48

20.0.0.0/30 is subnetted, 1 subnets

C 20.0.0.0 is directly connected, Serial0/0

192.168.2.0/30 is subnetted, 1 subnets

B 192.168.2.0 [20/0] via 20.0.0.2, 00:27:02

R2#sh ip route vrf local | begin Gateway

Gateway of last resort is not set

200.200.200.0/32 is subnetted, 1 subnets

O 200.200.200.1 [110/11] via 50.50.50.2, 00:15:52, FastEthernet0/0

50.0.0.0/30 is subnetted, 1 subnets

C 50.50.50.0 is directly connected, FastEthernet0/0

Question is if it possible to to import local vrf into global vrf?

One case is:

router bgp 1

address-family ipv4 vrf local

redistribute ospf 1 vrf local

But how to do this without BGP and only with OSPF?

Thank you.

Hi Donatas,

Unfortunately, I am afraid that this is not possible without BGP. The redistribution between VRFs is not supported with IGP protocols. Even if VRFs are used only locally and no VPNv4/MPLS VPNs are used, redistributing routes from one local VRF to another requires you to run the BGP process.

I am not aware of any other way of dynamically redistributing the networks between VRFs in a VRF-lite deployment.

Best regards,

Peter
