More than one PIM-SM router may be connected to an Ethernet or
other shared-media LAN. If multicast hosts are directly connected to
the LAN, then only one of these routers is elected as the DR, and acts
on behalf of these hosts, sending periodic Join/Prune messages toward
a group-specific RP for each group. A single DR is elected per interface
(LAN or otherwise) using a simple election process.
The router with the highest priority configured on an interface is elected
as the DR. If more than one router attached to this interface uses the
same priority, then the router with the highest IP address is elected to
serve as the DR.
If a router does not advertise a priority in its hello messages, it is
assumed to have the highest priority and is elected as the DR. If more
than one router is not advertising its priority, then the router with the
highest IP address is elected to serve as the DR.
