Switch# configure terminal
Switch (config)# ip vrf cisco
Switch (config-vrf)# rd 100:1
Switch (config-vrf)# exit
Switch (config)# interface Loopback0
Switch (config-if)# ip vrf forwarding cisco
Switch (config-if)# ip address 10.0.0.2 255.0.0.0
Switch (config-if)# exit
Switch (config-sg-tacacs+)# ip vrf forwarding cisco
Switch (config-sg-tacacs+)# ip tacacs source-interface Loopback0
Switch (config-sg-tacacs)# exit

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
| | }
import both

Purpose
Configures the VRF reference of a AAA TACACS+ server
group.
Uses the IP address of a specified interface for all outgoing
TACACS+ packets.
Exits server-group configuration mode.
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.
