Chapter 36 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.

VRF.
Configuring Multicast VRFs
Beginning in privileged EXEC mode, follow these steps to configure a multicast within a VRF table. For
complete syntax and usage information for the commands, see the switch command reference for this
release and the Cisco IOS Switching Services Command Reference, Release 12.2.

and an arbitrary number (xxx:y) or an IP address and an arbitrary
number (A.B.C.D:y). The route-target-ext-community should be the
same as the route-distinguisher entered in Step 4.
