OSPF PROTOCOL CONFIGURATION IN CISCO PACKET TRACER

OSPF PROTOCOL CONFIGURATION IN CISCO PACKET TRACER

The steps to set up the RIP is same to some extent as setting a router network link explained in the previous blog. The further steps to follow are given below:

Type no IP route network_ip network_subnet gateway_router_address.

(e.g.): no IP route 192.168.100.0 255.255.255.0 10.10.10.20

Then type router OSPF process_id. (*here process id is any number such as 99).

Then type network network_ip_address wild_mask area area_number.

(wild_mask is inverted subnet mask and area_number is process_id declared above).

OSPF is abbreviated as Open Shortest Path First. It is an intra-domain routing protocol and aso the implementation of link state routing protocol.It falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). OSPF was designed as an interior gateway protocol. It is used in an autonomous system such as a local area network (LAN).

To handle routing efficiently and on time, this protocol divides an autonomous system into areas. Area is a collection of routers, hosts, networks, all contained within an autonomous system. An autonomous system can be divided into many different areas, but at the same time, all networks inside an area must be connected.
