Configuration procedure
To configure an interface as a static member interface:
Ste
Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure the interface as a
static member interface.
igmp static-group group-address
[ source source-address ]
By default, an interface is not a
static member of any multicast
group or multicast source and
group.
Configuring a multicast group filter
To prevent the hosts attached to an interface from joining certain multicast groups, you can specify an
ACL on the interface as a packet filter. As a result, the receive hosts attached to this interface can join only
the multicast groups that the ACL permits.
To configure a multicast group filter:
Ste
Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure a multicast group
filter.
igmp group-policy acl-number
[ version-number ]
By default, no multicast group filter
is configured on any interface.
Hosts attached to an interface can
join any multicast group.
NOTE:
If you configure the interface as a static member interface for a multicast
roup or a multicast source and
group, this configuration is not effective on the multicast group or the multicast source and group.
Adjusting IGMP performance
Before adjusting IGMP performance, complete the following tasks:
• Configure any unicast routing protocol so that all devices are interoperable at the network layer.
• Configure basic IGMP functions.
Enabling IGMP fast-leave processing
In some applications, such as ADSL dial-up networking, only one multicast receiver host is attached to an
interface of the IGMP querier. The receiver host might switch frequently from one multicast group to
another. To allow fast response to the leave messages of the receiver host, you can enable fast-leave
processing on the IGMP querier.
