ip igmp snooping querier
Use this command to enable IGMP querier operation when no multicast routing protocol
is configured. When enabled, the IGMP Snooping querier sends out periodic IGMP queries
for all interfaces. This command applies to interfaces configured for IGMP Snooping.
Use the no variant of this command to disable IGMP querier configuration.
Syntax
ip igmp snooping querier
no ip igmp snooping querier
Mode
Interface Configuration for a VLAN interface.
Usage
The IGMP Snooping querier uses the 0.0.0.0 Source IP address because it only
masquerades as a proxy IGMP querier for faster network convergence.
It does not start, or automatically cease, the IGMP Querier operation if it detects query
message(s) from a multicast router.
If an IP address is assigned to a VLAN, which has IGMP querier enabled on it, then the IGMP
Snooping querier uses the VLAN’s IP address as the Source IP Address in IGMP queries.
The IGMP Snooping Querier will not stop sending IGMP Queries if there is another IGMP
Snooping Querier in the network with a lower Source IP Address.
Ensure your VLAN is configured first: see
Example
Validation
Commands
show ip igmp interface
show running-config
Note
Do not enable the IGMP Snooping Querier feature on a Layer 2 switch when
there is an operational IGMP Querier in the network.
