VRF Examples
The following examples show how to create VRFs for the examples in this document. In each VRF example, a VRF instance is created and then an interface in the VRF space is created for each entity in the communication loop. An OSPF is configured for the VRF to enable routing exchanges between the two entities. You can verify the configuration by using the show ip route vrf command.
