• You can enable IGMP snooping fast-leave processing either for the current port in interface view or
globally for all ports in IGMP-snooping view. If the configurations are made both in interface view
and IGMP-snooping view, the configuration made in interface view takes priority.

Disabling a port from becoming a dynamic router port
The following problems might exist in a multicast access network:
• After receiving an IGMP general query or a PIM hello message from a connected host, a router port
becomes a dynamic router port. Before its timer expires, this dynamic router port receives all
multicast packets within the VLAN where the port belongs and forwards them to the host. It
adversely affects multicast traffic reception of the host.
• The IGMP general query or PIM hello message that the host sends affects the multicast routing
protocol state on Layer 3 devices, such as the IGMP querier or DR election. This might further cause
network interruption.
To solve these problems and to improve network security and the control over multicast users, you can
disable that router port from becoming a dynamic router port.
To disable a port from becoming a dynamic router port:

port.
igmp-snooping router-port-deny
[ vlan vlan-list ]
By default, a port can become a
dynamic router port.
This configuration does not affect
the static router port configuration.
