Configuring A Multicast Group Filter; Adjusting Igmp Performance; Enabling Igmp Fast-Leave Processing - HP 6125XLG Ip Multicast Configuration Manual

Configuration procedure
To configure an interface as a static member interface:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the interface as a
static member interface.

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:
Step
1. Enter system view.
2. Enter interface view.
3. Configure a multicast group
filter.
NOTE:
If you configure the interface as a static member interface for a multicast group 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.

By default, an interface is not a
static member of any multicast
group or multicast source and
group.

By default, no multicast group filter
is configured on any interface.
Hosts attached to an interface can
join any multicast group.
