(Optional) Configuring IGMP

Enable the Internet Group Management Protocol (IGMP) on a multicast device's interface that is connected to users, implementing multicast group member management on the local network.

Context

IGMP, a protocol in the TCP/IP protocol suite, manages IPv4 multicast group members. IGMP sets up and maintains multicast group member relationships between IP hosts and neighboring multicast routers directly connected to the hosts.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.

interface-type interface-number specifies an interface connected to user hosts.
Run pim sm
PIM is enabled.
Run igmp enable
IGMP is enabled.
Run commit
The configuration is committed.

Follow-up Procedure

Configure an IGMP version, create a static multicast group, or specify the multicast groups to which interfaces are allowed to be added. For details, see IGMP Configuration.
