OSPF interface
Note:
The DR priorities configured by the ospf dr-priority command and the peer command
have different purpose:
The priority set with the ospf dr-priority command is used for actual DR election.
The priority set with the peer command is used to indicate if a neighbor has the right
to vote. If you specify the priority to 0 when configuring a neighbor, the local router
will believe that the neighbor has no right to vote and sends no Hello packet to it.
This configuration can reduce the number of Hello packets on the network during
the election of DR and BDR. However, if the local router is already a DR or BDR, it
will send Hello packets to the neighbor whose DR priority is 0 to establish the
neighboring relationship.
