Information About GRE Tunnel IP Source and Destination VRF
Membership
This feature allows you to configure the source and destination of a tunnel to belong to any Virtual Private
Network (VPN) routing and forwarding (VRF) table. A VRF table stores routing data for each VPN. The
VRF table defines the VPN membership of a customer site attached to the network access server (NAS). Each
VRF table comprises an IP routing table, a derived Cisco Express Forwarding (CEF) table, and guidelines
and routing protocol parameters that control the information that is included in the routing table.
Previously, GRE IP tunnels required the IP tunnel destination to be in the global routing table. The
implementation of this feature allows you to configure a tunnel source and destination to belong to any VRF.
As with existing GRE tunnels, the tunnel becomes disabled if no route to the tunnel destination is defined.
