Configuring IGMP Snooping and MVR
This chapter describes how to configure Internet Group Management Protocol (IGMP) snooping on the
switch, including an application of local IGMP snooping, Multicast VLAN Registration (MVR). It also
includes procedures for controlling multicast group membership by using IGMP filtering and procedures
for configuring the IGMP throttling action.
For IP Version 6 (IPv6) traffic, Multicast Listener Discovery (MLD) snooping performs the same
Note
function as IGMP snooping for IPv4 traffic. For information about MLD snooping, see
"Configuring IPv6 MLD Snooping."
Note For complete syntax and usage information for the commands used in this chapter, see the switch
command reference for this release and the "IP Multicast Routing Commands" section in the Cisco IOS
IP Command Reference, Volume 3 of 3:Multicast, Release 12.2 from the Cisco.com page under
Documentation > Cisco IOS Software > 12.2 Mainline > Command References.
