OSPF Overview

OSPF is becoming the preferred IGP
protocol when compared with RIPv1 and
RIPv2 because it is scalable.

Setting OSPF Priority

The priorities can be set to any value from 0 to 255. A value
of 0 prevents that router from being elected. A router with
the highest OSPF priority will win the election for DR
.
