30.1.1.7 Configuring Querier of IGMP-Snooping
If the multicast router does not exist in VLAN where IGMP-snooping is activated, the querier function of
IGMP-snooping can be used to imitate the multicast router to regularly send IGMP query message. (The
function is global, that is, it can be enabled or disabled in VLAN where IGMP-snooping is globally enabled)
When the multicast router does not exist in LAN and multicast flow does not need routing, the automatic query
function of the switch can be activated through IGMP snooping, enabling IGMP snooping to work properly.
Perform the following configuration in global configuration mode:
Command Description
[no] ip igmp-snooping querier
[address[ip_addr]
Configures the querier of IGMP-snooping. The optional
parameter address is the source IP address of query
message.
The IGMP-snooping querier function is disabled by default. The source IP address of fake query message
is 10.0.0.200 by default.
If the querier function is enabled, the function is disabled when the multicast router
exists in VLAN; the function can be automatically activated when the multicast
router times out.
