multicast routing protocol that runs on the LAN. But for IGMP
Version 2, the designated querier is the lowest IP-addressed multicast
router on the subnet.
Example
The following shows how to configure the query interval to 100 seconds:
ip igmp max-resp-interval
Use this command to configure the maximum response time advertised in
IGMP queries. Use the no form of this command to restore the default.
Syntax
ip igmp max-resp-interval seconds
no ip igmp max-resp-interval
seconds - The report delay advertised in IGMP queries. (Range:
1-255)
Default Setting
10 seconds
Command Mode
Interface Configuration (VLAN)
Command Usage
• The switch must be using IGMPv2 for this command to take effect.
• This command defines how long any responder (i.e., client or router)
still in the group has to respond to a query message before the router
deletes the group.
• By varying the Maximum Response Interval, you can tune the
burstiness of IGMP messages passed on the subnet; where larger
values make the traffic less bursty, as host responses are spread out
over a larger interval.
