4.3 OSPF- Open Shortest Path First
OSPF is a link state protocol and it uses Dijkstra’s Shortest Path First algorithm to run on the
link state database. This technology is opposed to a distance-vector technology. OSPF router
protocol is interior gateway router protocol that used to make decision on routes in
Autonomous system. The link state protocol is use a cost metric to determine the best path to
a destination.
When router or network’s topology start to change the routing protocol will generate a LSA and
flood it to notify the area or network that belongs.
Types of area
Standard area – This area can accept intra-area, inter-area and external router. This area also
can be backbone area.
Backbone area – the backbone (transit) area always labeled area 0. Backbone area is a
central entity that contains all other area. The backbone is responsible for distributing routing
