Step 2
multicast-routing
Example:
RP/0/0/CPU0:router(config)#
multicast-routing
RP/0/0/CPU0:router(config-mcast)#
Step 3
mdt source loopback
interface-path-id
Example:
RP/0/0/CPU0:router(config-mcast)#
mdt source loopback 0
Step 4
vrf vrf-name mdt source loopback
interface-path-id
Example:
RP/0/0/CPU0:router(config-mcast)#
vrf 101 mdt source loopback 1
Step 5
Repeat the foregoing step as many times
as needed to create other VRFs.
Example:
RP/0/0/CPU0:router(config-mcast)#
vrf 102 mdt source loopback 2
Multicast Configuration Guide
MCC-48
This is the default VRF.
Note
vrf vrf-name mdt source loopback interface-path-id
This is the first specified VRF.
Note
Repeat the foregoing step as many times as needed to create other VRFs.

Implementing Multicast Routing on Cisco IOS XR Software Cisco ASR 9000 Series Routers
Purpose
Enters global configuration mode.
Enables IP multicast routing and forwarding.
Configures the interface used to set the MDT source
address for MVPN, using the default VRF.
Note The MDT source command under default VRF
is required to enable MVPN.
Configures a second interface by specifying a
particular VRF on a loopback to override the default
VRF.
