Overview of OSPF
OSPF point-to-point Links
One important OSPF process is Adjacency. Adjacency occurs when a relationship is formed
between neighboring routers for the purpose of exchanging routing information. Adjacent OSPF
neighbor routers go beyond the simple Hello packet exchange; they exchange database
information. In order to minimize the amount of information exchanged on a particular segment,
one of the first steps in creating adjacency is to assign a Designated Router (DR) and a Backup
Designated Router (BDR). The Designated Router ensures that there is a central point of contact,
thereby improving convergence time within a multi-access segment.
