• Determine the multicast group and multicast source addresses for static group member
configuration.
• Determine the ACL for multicast group filtering.
Enabling IGMP
To configure IGMP, enable IGMP on the interface where the multicast group memberships are
established and maintained.
To enable IGMP:
Step 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:
Step 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
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.
Configuration guidelines
• An IGMP-enabled static member interface has the following restrictions:
{
If it is enabled with PIM-SM, it must be a PIM-SM DR.
{
If it is not enabled with PIM-SM, it must be an IGMP querier.
For more information about PIM-SM and DR, see " Configuring PIM ."
