• Determine the maximum number of multicast groups that an interface can join.
Enabling IGMP
To configure IGMP, you must enable IGMP on the interface where the multicast group memberships will
be established and maintained.
To enable IGMP:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enable IP multicast routing.
multicast routing-enable Disabled by default.
3. Enter interface view.
interface interface-type interface-number N/A
4. Enable IGMP.
igmp enable Disabled by default.
Specifying the version of IGMP
Because the protocol packets of different IGMP versions vary in structure and type, you must specify the
same IGMP version for all routers on the same subnet. Otherwise, IGMP cannot work correctly.
To specify the global version of IGMP:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter public network IGMP view.
igmp N/A
3. Specify the global version of IGMP.
version version-number IGMPv2 by default.

Configuring an interface as a static member interface
You can configure an interface as a static member of a multicast group or a multicast source and group,
so that the interface can receive multicast data addressed to that multicast group for the purpose of
testing multicast data forwarding.
When you configure an interface as a static member interface, follow these guidelines:
• When you configure an interface on a PIM-SM device as a static member interface, if the interface
is PIM-SM enabled, the interface must be a PIM-SM DR. If the 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
"Configuring PIM."
• A static member interface does not re
spond to queries that the IGMP querier sends. When you
configure an interface as a static member or cancel this configuration on the interface, the interface
does not unsolicitedly send any IGMP report or IGMP leave message. In other words, the interface
is not a real member of the multicast group or the multicast source and group.
