Example
The following example configures the multicast router timeout to 200 seconds.
console(config)# interface vlan 2
console(config-if)# ip igmp snooping mrouter-time-out 200
ip igmp snooping leave-time-out
The ip igmp snooping leave-time-out Interface Configuration (VLAN) mode command configures
the leave-time-out. When a group-specific IGMPv2 leave message is received, IGMP snooping
removes the interface after 10 sec from the Layer 2 forwarding table entry for that multicast group.
To configure the default leave-time-out, use the no form of this command.
