Enabling IGMP
To configure IGMP, enable IGMP on the interface where the multicast group memberships are
established and maintained.
To enable IGMP:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enable IP multicast routing
and enter MRIB view.
multicast routing [ vpn-instance
vpn-instance-name ]
By default, IP multicast is disabled.
3. Return to system view.
quit N/A
4. Enter interface view.
interface interface-type
interface-number
N/A
5. Enable IGMP.
igmp enable By default, IGMP is disabled.
Specifying the IGMP version
Because the protocol packets of different IGMP versions vary in structure and type, specify the same
IGMP version for all routers on the same subnet. Otherwise, IGMP cannot operate correctly.
To specify an IGMP version:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Specify an IGMP version.
igmp version version-number The default setting is IGMPv2.
Configuring an interface as a static member interface
To test the multicast data forwarding, you can configure an interface as a static member of a multicast
group or a multicast source and group. The interface will receive multicast data addressed to that
multicast group.
Configuration guidelines
• A static member interface has the following restrictions:
{ If the interface is IGMP and PIM-SM enabled, it 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 DR, see "Configuring PIM."
• A stati
c member interface does not respond to queries that the IGMP querier sends. When you
configure an interface as a static member or cancel this configuration, the interface does not send
any IGMP report or IGMP leave message. This is because the interface is not a real member of the
multicast group or the multicast source and group.
