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 ]
Required
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 “PIM configruation.”
• As a static member of a multicast group or a multicast source and group, the interface does not respond
to the queries from the IGMP querier, nor does it send an unsolicited IGMP membership report or an
IGMP leave group message when it joins or leaves a multicast group or a multicast source and group.
In other words, the interface will not become 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
matching the criteria.
Follow these steps to configure a multicast group filter:

Adjusting IGMP performance
NOTE:
For the configuration tasks described in this section:
• Confi
g
urations performed in IGMP view are effective on all interfaces, while confi
g
urations performed
in interface view are effective on the current interface only.
• If the same feature is configured in both IGMP view and interface view, the confi
g
uration performed in
interface view is given priority, regardless of the configuration sequence.
Configuration prerequisites
Before adjusting IGMP performance, complete the following tasks:
