IGMP Configuration Guidelines

To configure IGMP, you include statements at the [edit protocols igmp] hierarchy level of the configuration:

[edit]

protocols {

    igmp {

        interface interface-name {

            disable; 

            static {

                group group {

                    source source; 

                }    

            }

            version version; 

        }

        query-interval seconds; 

        query-last-member-interval seconds; 

        query-response-interval seconds; 

        robust-count number; 

        traceoptions {

            file name <replace> <size size> <files number> <no-stamp> 

                <(world-readable | no-world-readable)>;

            flag flag <flag-modifier> <disable>; 

        }

    } 

} 

By default, IGMP is automatically enabled on all broadcast interfaces on which you configure DVMRP or PIM.
