The DR priority configured with the ospf dr-priority command and the one configured with the peer
command have the following differences:
z
The former is for actual DR election.
z
The latter is to indicate whether a neighbor has the election right or not. If you configure the DR
priority for a neighbor as 0, the local router will consider the neighbor has no election right, and thus
no hello packet is sent to this neighbor, reducing the number of hello packets for DR/BDR election
on networks. However, if the local router is the DR or BDR, it sends hello packets to the neighbor
with priority 0 for adjacency establishment.
