Command or Action
Step 9
root
Example:
RP/0/RSP0/CPU0:router(config-vrf-af)# root
Step 10
multicast-routing vrf vrf_name
Example:
RP/0/RSP0/CPU0:router(config)#
multicast-routing vrf vrf1
Step 11
address-family [ipv4 | ipv6 ]
Example:
RP/0/RSP0/CPU0:router(config-mcast-vrf1)#
address-family ipv4
Step 12 mdt default mldp ipv4 root-node
Example:
RP/0/RSP0/CPU0:router(config-mcast-vrf1-ipv4)#
mdt default mldp ipv4 2.2.2.2
Step 13 mdt data mdt-group-address threshold value
Example:
RP/0/RSP0/CPU0:router(config-mcast-vrf1-ipv4)#
mdt data 239.0.0.0/24 threshold 1000
Step 14 root
Example:
RP/0/RSP0/CPU0:router(config-mcast-vrf1-ipv4)#

Cisco ASR 9000 Series Aggregation Services Router Multicast Configuration Guide, Release 5.1.x
Purpose
Takes the user to the global configuration level.
Enables multicast routing for the specified VRF.
Enters the address-family submode.
Configures MLDP MDT for a VRF. The root node can be
IP address of a loopback or physical interface on any router
(source PE, receiver PE or core router) in the provider
network. The root node address should be reachable by all
the routers in the network. The router from where the
signalling occurs functions as the root node.
The default MDT must be configured on each PE router to
enable the PE routers to receive multicast traffic for this
particular MVRF.
By default MPLS MLDP is enabled. To disable,
Note
use the no mpls ldp mldp command.
LSPVIF tunnel is created as a result of mdt default
Note
mldp root-node command.
Configures the threshold value for data MDT.
Takes the user to the global configuration mode.
