Configuring a Designated Router
Multiple PIM-SM routers might be connected to a single local area network (LAN) segment. One of these routers is elected to
act on behalf of directly connected hosts. This router is the designated router (DR).
The DR is elected using hello messages. Each PIM router learns about its neighbors by periodically sending a hello message out
of each PIM-enabled interface. Hello messages contain the IPv4 address of the interface out of which it is sent and a DR priority
value. The router with the greatest priority value is the DR. If the priority value is the same for two routers, then the router with
the greatest IPv4 address is the DR. By default, the DR priority value is 192, so the IP address determines the DR.
● Assign a DR priority value.
INTERFACE mode
ip pim dr-priority priority-value
● Change the interval at which a router sends hello messages.
INTERFACE mode
ip pim query-interval seconds
● Display the current value of these parameter.
