On a multi-access network such as an Ethernet, one of the PIM routers
is elected as a Designated Routers (DR). The PIM DR has two roles in
the PIM protocol. On the first hop network, the PIM DR is
responsible for registering an active source to the RP if the group
is operated in PIM SM. On the last hop network, the PIM DR is
responsible for tracking local multicast listeners and forwarding
traffic to these listeners if the group is operated in PIM SM/SSM/DM.
In this document, we propose a modification to the PIM protocol that
allows multiple of these last hop routers to be selected so that the
forwarding load can be distributed to and handled among these
routers. A router responsible for forwarding for a particular group
is called a Group Designated Router (GDR).
