24.2.1 References
The IGMP module is based on the following RFC:
RFC 1112
RFC 2236
24.2.2 Configuring IGMP Parameter
There is no explicit command to enable IGMP, which is always combined with PIM-SM.
When PIM-SM is enabled on an interface, IGMP will be enabled automatically on this
interface, vice versa. But notice, before IGMP can work, IP Multicast-routing must be
enabled globally firstly.
