Configuring Multicast VRFs

To configure multicast within a VRF table, perform this task:
Command
Switch# configure terminal
Step 1
Switch(config)# ip routing
Step 2
Switch(config)# ip vrf vrf-name
Step 3
Switch(config-vrf)# ip
Step 4
multicast-routing vrf vrf-name
Switch(config-vrf)# rd
Step 5
route-distinguisher
Switch(config-vrf)# route-target
Step 6
{
export
route-target-ext-community
Switch(config-vrf)# import map
Step 7
route-map
Switch(config-vrf)# interface
Step 8
interface-id
Switch(config-if)# ip vrf forwarding
Step 9
vrf-name
Switch(config-if)# ip address
Step 10
ip-address mask
Switch(config-if)# ip pim
Step 11
[sparse-dense mode | dense-mode |
sparse-mode]
Switch(config-if)# end
Step 12
Switch# show ip vrf
Step 13
interfaces
Switch# copy running-config
Step 14
startup-config
For more information about configuring a multicast within a Multi-VRF CE, see the
Cisco IOS IP Multicast Configuration Guide, Release 12.4.
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.

Purpose
Enters global configuration mode.
Enables IP routing.
Names the VRF and enters VRF configuration mode.
(Optional) Enables global multicast routing for VRF table.
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 arbitrary number
(A.B.C.D:y).
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 value should be the same
as the route-distinguisher value entered in Step 4.
(Optional) Associates a route map with the VRF.
Enters interface configuration mode and specifies the
Layer 3 interface to be associated with the VRF. The
interface can be a routed port or a SVI.
Associates the VRF with the Layer 3 interface.
Configures IP address for the Layer 3 interface.
Enables PIM on the VRF-associated Layer 3 interface.
Returns to privileged EXEC mode.
