Configuring an IGMP Querier IP Address


You can configure an IGMP querier IP address for a VLAN or as a global IGMP querier. The IGMP querier sends IGMP General Query messages. on the network.

If no querier IP address is specified, then 0.0.0.0 is the default value. There can be an unique querier IP for each VLAN, or you can configure the same Querier IP address for all the VLANs participating in IGMP snooping. The Querier IP address should have a local scope and every switch should have a unique Querier IP address.  


With a valid source IP address on IGMP Query packets, the VLAN, where Query is received, is added to an IGMP Snoop switch list, and is now reflected in the igmp-switches-show output and the IGMP queries are sent to the peer Switch as well. This is to solicit a report from the hosts listening on the peer switch.
