Configuring Multicast Vrf Routing - Cisco WS-SUP32-GE-3B - Supervisor Engine 32 Software Configuration Manual

Chapter 22 Configuring IPv4 Multicast VPN Support
To display information about the multicast routing table and tunnel interface for a particular MVRF, use
the show ip mroute vrf command. The following example shows typical output for a MVRF named
BIDIR01:
Router# show ip mroute vrf BIDIR01
IP Multicast Routing Table
Flags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected,
Outgoing interface flags: H - Hardware switched
Timers: Uptime/Expires
Interface state: Interface, Next-Hop or VCD, State/Mode
(*, 228.1.0.1), 00:16:25/stopped, RP 10.10.10.12, flags: SJCF
Incoming interface: Tunnel1, RPF nbr 10.10.10.12, Partial-SC
Outgoing interface list:
(6.9.0.100, 228.1.0.1), 00:14:13/00:03:29, flags: FT
Incoming interface: GigabitEthernet3/1.3001, RPF nbr 0.0.0.0, RPF-MFD
Outgoing interface list:
Router#
In this example, the show ip mroute vrf command shows that Tunnel1 is the MDT tunnel interface
Note
(MTI) being used by this VRF.

Configuring Multicast VRF Routing

These sections describe how to configure multicast routing to support MVPN:

BGP should be already configured and operational on all routers that are sending or receiving multicast

traffic. In addition, BGP extended communities must be enabled (using the neighbor send-community
both or neighbor send-community extended command) to support the use of MDTs in the network.
