Information
Queriers normally send a certain number of queries when a leave message is received prior to deleting
a group from the membership database. There may be situations in which fast deletion of a group is
required. When you enable IGMP fast leave processing, the switch removes an interface from the
multicast group as soon as it detects an IGMP version 2 leave message on the interface.
ip igmp snooping flood
This command controls the flooding behavior of unregistered multicast data packets.When flooding is
disabled, unregistered multicast data traffic is forwarded to only multicast router ports, both static and
dynamic, in a VLAN. If there is no multicast router port in a VLAN, unregistered multicast data traffic
is dropped.
On the MXL Switch, when you configure no ip igmp snooping flood, the system forwards the frames
on mrouter ports for first 96 IGMP snooping enabled VLANs. For all other VLANs, unregistered
multicast packets are dropped.
