15.2.7 Static group participation

Use static group joining functionality to forward IP multicast packets on networks without hosts supporting IGMP.

Interfaces for which static group joining is set run the same as those that have joined groups, without receiving any Membership Reports.

Because this functionality belongs to IGMPv2, it does not work if the IGMP version of the corresponding interface is set to version 3 only. Likewise, if version 3 is set, this functionality runs the same as that for group joining under IGMPv2.
