Use this procedure to enable IP Multicast over Fabric Connect on a brouter port. The default is disabled.
To configure a brouter port for IP Shortcuts with IP Multicast over Fabric Connect, see Configure IP Multicast over Fabric Connect on a Brouter Port within the GRT.
You must configure the required SPBM and IS-IS infrastructure, which includes the creation of SPBM B-VLANs.
You must configure a VRF and an IP VPN instance with an I-SID configured under it on the switch. The IP VPN does not need to be enabled for Layer 2 VSN multicast to function.
You must enable IP Multicast over Fabric Connect globally.
If there is no IP interface on the VLAN, then you create one. (The IP interface must be in the same subnet as the IGMP hosts that connect to the VLAN).
You must enable MVPN for the particular VRF.
You must enable IP Multicast over Fabric Connect on each of the VLANs that need to support IP multicast traffic.
If you only want to use IP Multicast over Fabric Connect, you do not need to enable the Layer 3 VSN or redistribute unicast routes into or out of IS-IS. IP Multicast over Fabric Connect routing does not depend on unicast routing, which allows for you to more easily migrate from a PIM environment to Multicast over Fabric Connect. You can migrate a PIM environment to IP Multicast over Fabric Connect first, and then migrate unicast separately or not at all.
The switch only supports IPv4 address with IP Multicast over Fabric Connect.
