Configuring Multicast VRFs Procedure Configuring Multi-VRF CE Configuring Multicast VRFs Command or Action Purpose Step 1 enable Example: Device>enable Enables privileged EXEC mode. Enter your password if prompted. Step 2 configure terminal Example: Device#configure terminal Enters global configuration mode. Step 3 ip routing Example: Device(config)#ip routing Enables IP routing mode. Step 4 ip vrf vrf-name Example: Device(config)#ip vrf vpn1 Names the VRF, and enter VRF configuration mode. Step 5 rd route-distinguisher Example: Device(config-vrf)#rd 100:2 Creates a VRF table by specifying a route distinguisher.
Enter either an AS number and an arbitrary number (xxx:y) or an IP address and an arbitrary number (A.B.C.D:y) Step 6 route-target {export | import | both} route-target-ext-community Example: Device(config-vrf)#route-target import 100:2 Creates a list of import, export, or import and export route target communities for the specified VRF. Enter either an AS system number 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. Step 7 import map route-map Example: Device(config-vrf)#import map importmap1 (Optional) Associates a route map with the VRF.
Step 8 ip multicast-routing vrf vrf-name distributed Example: (Optional) Enables global multicast routing for VRF table. Configuring Multi-VRF CE 7
