Required
An interface is not a static
member of any multicast
group by default.
 Note:
z Before you can configure an interface of a PIM-SM device as a static member of a
multicast 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, refer to
DR election.
z As a static member of a multicast group, an 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. In
other words, the interface will not become a real member of the multicast group.
4.3.5 Configuring an IGMP Multicast Group Filter
IGMP multicast group filtering is implemented by an IGMP-Snooping multicast group
filter. For details, see
Configuring an IGMP-Snooping Multicast Group Filter.
4.4 Adjusting IGMP Performance
 Note:
For the configuration tasks described in this section:
z Configurations performed in IGMP view are effective on all interfaces, while
configurations performed in interface view are effective on the current interface only.
z If the same feature is configured in both IGMP view and interface view, the
configuration performed in interface view is given priority, regardless of the
configuration sequence.
