ip igmp snooping immediate-leave
This command enables IGMP immediate leave for specific VLAN. Use
the no form to disable the feature for a VLAN.
Syntax
[no] ip igmp snooping immediate-leave
Default Setting
Disabled
Command Mode
Interface Configuration (VLAN)
Command Usage
The IGMP snooping immediate-leave feature enables a Layer 2 LAN
interface to be removed from the multicast forwarding table without
first sending an IGMP group-specific query to the interface. Upon
receiving a group-specific IGMPv2 leave message, the switch
immediately removes the interface from the Layer 2 forwarding table
entry for that multicast group, unless a multicast router was learned on
the port.
Example
show ip igmp snooping
This command shows the IGMP snooping configuration.
Default Setting
None
Command Mode
Privileged Exec
Console(config)#interface vlan 1
Console(config-if)#ip igmp snooping immediate-leave
