Implementing Multicast Routing on Cisco IOS XR Software
Purpose
Enables multicast routing for the specified VRF.
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, use the
Note
no mpls ldp mldp command.
LSPVIF tunnel is created as a result of mdt default mldp
Note
root-node command.
Configures the threshold value for data MDT.
Enters the BGP configuration mode.
Creates routing and forwarding tables. Specify the
route-distinguisher argument to add an 8-byte value to an IPv4
prefix to create a VPN IPv4 prefix. You can enter an RD value
in either of these formats:
• 16-bit autonomous system number. For example, 101:3.
• 32-bit IP address: your 16-bit number. For example,
192.168.122.15:1.
Configures the BGP MDT address family.
