31.2.7 Static group participation

Use the static group join functionality to forward IPv6 multicast packets on networks without hosts that support MLD.

Interfaces for which static group joining is set run in the same way (without receiving any Multicast Listener Reports) as interfaces that have joined groups.

Because this functionality belongs to MLDv1, it does not work when the MLD version of the corresponding interface is set to version 2 only. Likewise, when version 2 is set, this functionality runs the same as the group join functionality under MLDv1.
