Chapter 38 Configuring IP Unicast Routing
Configuring Multi-VRF CE
Use the no ip vrf vrf-name global configuration command to delete a VRF and to remove all interfaces
from it. Use the no ip vrf forwarding interface configuration command to remove an interface from the
VRF.
from it. Use the no ip vrf forwarding interface configuration command to remove an interface from the
VRF.
Configuring a VPN Routing Session
Routing within the VPN can be configured with any supported routing protocol (RIP, OSPF, EIGRP, or
BGP) or with static routing. The configuration shown here is for OSPF, but the process is the same for
other protocols.

Beginning in privileged EXEC mode, follow these steps to configure OSPF in the VPN:
Use the no router ospf process-id vrf vrf-name global configuration command to disassociate the VPN
forwarding table from the OSPF routing process.
