Configure the required SPBM and IS-IS infrastructure, which includes the creation of SPBM B-VLANs.
Create the C-VLANs and add slots/ports.
Enable IP Multicast over Fabric Connect globally.
Assign an I-SID for the IPVPN.
Use this procedure to configure IP Multicast over Fabric Connect for a Layer 3 VSN.
You cannot enable IP PIM when IP Multicast over Fabric Connect is enabled on the VLAN.
The IP VPN does not need to be enabled for Layer 3 VSN multicast to function.
The switch only supports IPv4 multicast traffic.
enable
configure terminal
interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]} or interface vlan <1–4059>
Note
If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
ip igmp snooping
ip igmp ssm-snoop
ip igmp compatibility-mode
ip igmp version 3
Note
IGMPv2 at the VLAN level is the default setting, with no other configuration required. You only need to use these commands if you use IGMPv3. You must enable SSM snoop before you configure IGMP version 3, and you must enable both ssm-snoop and snooping for IGMPv3.
For IGMP Snooping, ensure that the IGMP version used by multicast hosts and other devices in the network is the same as the IGMP version configured on the IGMP Snooping VLAN, or that you enable compatibility mode.
ip igmp snoop-querier-addr {A.B.C.D}
Note
If the SPBM bridge connects to an edge switch, it can be necessary to add an IGMP query address. If you omit adding a query address, the SPB bridge sends IGMP queries with a source address of 0.0.0.0. Some edge switch models do not accept a query with a source address of 0.0.0.0.
Configure IP Multicast over Fabric Connect for a Layer 3 VSN:
