Configuring Basic Igmp Functions; Enabling Igmp; Configuring Igmp Versions - HP 6125G Configuration Manual

If a feature is not configured on an interface in interface view, the global configuration in IGMP
•
view will apply to that interface. If a feature is configured in both IGMP view and interface view, the
configuration in interface view will be given priority.

Configuring basic IGMP functions

Before you configure basic IGMP functions, complete the following tasks:
Configure any unicast routing protocol so that all devices in the domain are interoperable at the
•
network layer.
• Configure PIM-DM or PIM-SM.
Determine the IGMP version.
•
Determine the multicast group and multicast source addresses for static group member
•
configuration.
Determine the ACL rule for multicast group filtering.
•
Determine the maximum number of multicast groups that an interface can join.
•

Enabling IGMP

To configure IGMP, you must enable IGMP on the interface for which the multicast group memberships
will be established and maintained.
Step
1. Enter system view.
2. Enable IP multicast routing.
3. Enter interface view.
4. Enable IGMP.

Configuring IGMP versions

Because the protocol packets of different IGMP versions vary in structure and type, you must configure the
same IGMP version for all routers on the same subnet before IGMP can work properly.
Configuring an IGMP version globally
Step
1. Enter system view.
2. Enter IGMP view.
3. Configure an IGMP version
globally.
