The example below shows the configuration steps to enable IP Multicast over Fabric Connect support on C-VLAN 1001 that is part of a Layer 2 VSN, including the querier address.
enable configure terminal ISIS SPBM CONFIGURATION router isis spbm 1 multicast enable VLAN CONFIGURATION interface vlan 9 ip igmp snooping ip igmp snoop-querier-addr 192.0.2.201 exit
When using IGMPv3, the configuration is:
enable configure terminal ISIS SPBM CONFIGURATION router isis spbm 1 multicast enable VLAN CONFIGURATION interface vlan 19 ip igmp snooping ip igmp version 3 ip igmp ssm-snoop ip igmp snoop-querier-addr 192.0.2.201 exit
Note
You must enable SSM snoop before you configure IGMP version to version 3, and you must enable both ssm-snoop and snooping for IGMPv3.
Note
You must configure basic SPBM and IS-IS infrastructure.
