3.

Configure the interface as a static

member of a multicast group or a
multicast source and group.

igmp static-group group-address
[ source source-address ]

An interface is not a static
member of any multicast
group or multicast source

and group by default.

NOTE:

Before you can configure an interface of a PIM-SM device as a static member of a multicast group or a
multicast source and group, if the interface is PIM-SM enabled, it must be a PIM-SM DR. If this interface
is IGMP enabled but not PIM-SM enabled, it must be an IGMP querier. For more information about

PIM-SM and a DR, see "Configuring PIM."

A static member port does not respond to queries from the IGMP querier. When you configure a port as
a static member port or remove this configuration on the port, the port does not unsolicitedly send any
IGMP report or IGMP leave message. In other words, the port is not a real member of the multicast

group or the multicast source and group.

Configuring a multicast group filter

To restrict the hosts on the network attached to an interface from joining certain multicast groups, you can

set an ACL rule on the interface as a packet filter so that the interface maintains only the multicast groups

the match the criteria.
