VRF Membership
•
Both ends of the tunnel must reside within the same VRF.
•
The VRF associated with the tunnel vrf command is the same as the VRF associated with the
physical interface over which the tunnel sends packets (outer IP packet routing).
•
The VRF associated with the tunnel by using the ip vrf forwarding command is the VRF that the
packets are to be forwarded in as the packets exit the tunnel (inner IP packet routing).
