Command History
Usage Guidelines The ip
vrf vrf-name command creates a VRF instance named vrf-name. To make the VRF functional, a
route distinguisher (RD) must be created using the rd route-distinguisher command in VRF
configuration mode. The rd route-distinguisher command creates the routing and forwarding tables and
associates the RD with the VRF instance named vrf-name.
The ip v
rf default command can be used to configure a VRF instance that is a NULL value until a default
VRF name can be configured. This is typically before any VRF related AAA commands are configured.
Examples The following example shows how to import a route map to a VRF instance named VPN1:
ip vrf vpn1
rd 100:2
route-target both 100:2
route-target import 100:1
vrf-name Name assigned to a VRF.
