Enabling IGMP

When multicast routing protocol is enabled, IGMP is enabled as well
Note
35.6 Advanced Multicast Routing
Configuration
Advanced multicast routing configuration includes:
Configuring multicast routing characteristics (optional)

Configuring IGMP task list(optional)

Configuring PIM-DM task list(optional)

Configuring DVMRP interoperability task list(optional)

35.6.1 Configuring Multicast Routing
Characteristics
35.6.1.1 Configuring TTL Threshold
Use ip multicast ttl-threshold to configure TTL threshold of multicast packet which is
allowed to transmit through the interface, and use no ip multicast ttl-threshold to deploy
the default value. The default value is 1.
When the multicast routing protocol is enabled on the interface, the IGMP
function is activated at the same time.
Hosts and routers of IGMP are activated simultaneously.
Chapter 35 IP Multicast Routing Configuration
Purpose
Enter the interface that needs to run PIM-DM and
enable PIM-DM multicast routing process in the
interface configuration mode.
