Step 7
Configuring the IGMP Snooping Querier (CLI)
Follow these guidelines when configuring the IGMP snooping querier:
•
Configure the VLAN in global configuration mode.
•
Configure an IP address on the VLAN interface. When enabled, the IGMP snooping querier uses the IP
address as the query source address.
•
If there is no IP address configured on the VLAN interface, the IGMP snooping querier tries to use the
configured global IP address for the IGMP querier. If there is no global IP address specified, the IGMP
querier tries to use the VLAN device virtual interface (SVI) IP address (if one exists). If there is no SVI
IP address, the device uses the first available IP address configured on the device. The first IP address
available appears in the output of the
show ip interface
privileged EXEC command. The IGMP snooping
querier does not generate an IGMP general query if it cannot find an available IP address on the device.
•
The IGMP snooping querier supports IGMP Versions 1 and 2.
•
When administratively enabled, the IGMP snooping querier moves to the nonquerier state if it detects
the presence of a multicast router in the network.
•
When it is administratively enabled, the IGMP snooping querier moves to the operationally disabled
state under these conditions:
◦
IGMP snooping is disabled in the VLAN.
◦
PIM is enabled on the SVI of the corresponding VLAN.
