16.1.9 Configuring IGMP

Points to note

IGMP must be configured for interfaces on which IGMP will run. However, IGMP also can run if IPv4 PIM-SM (sparse mode) is set on an interface.

By default, IGMP uses a mixed mode of versions 2 and 3. Use the ip igmp version configuration command to change the IGMP version.

Command examples

1. (config-if)# ip igmp router

   Specifies that IGMP runs on the target interface in mixed mode for versions 2 and 3 (default).
