Syntax show ip igmp snooping mrouter Default Configuration This command has no default configuration. Command Mode User EXEC, Privileged EXEC modes, Config mode and all Config sub-modes User Guidelines This command has no user guidelines. Example The following example shows IGMP snooping mrouter information. console#show ip igmp snooping mrouter VLAN ID ------10 Port ----------Gi2/0/1 ip igmp snooping vlan immediate-leave This command enables or disables IGMP Snooping immediate-leave mode on a selected VLAN. Enabling immediate-leave allows the switch to immediately remove the layer 2 LAN interface from its forwarding table entry upon receiving an IGMP leave message for that multicast group without first sending out MAC-based general queries to the interface. The no form of this command disables IGMP Snooping immediate-leave mode on a VLAN. You should enable immediate-leave admin mode only on VLANs where only one host is connected to each layer 2 LAN port. This setting prevents the inadvertent dropping of the other hosts that were connected to the same layer 2 LAN port but were still interested in receiving multicast traffic directed to that group. Also, immediate-leave processing is supported only with IGMP version 2 hosts. IGMP Snooping Commands 473
