OSPF protocol configuration in cisco packet tracer

The OSPF (Open Shortest Path First) protocol is one of a family of IP Routing protocols, and is an Interior Gateway Protocol (IGP) for the Internet, used to distribute IP routing information throughout a single Autonomous System (AS) in an IP network.

Fig 1:Ospf config

Procedure:

1.      Define the following topology in cisco packet tracer.

2.      Assign IP addresses to the network devices:

      3 . configure router interfaces and switch ports:

For router 0:

Router(config)#int gig 0/1

Router(config-if)#ip add 10.0.0.2 255.0.0.0

Router(config-if)#no shut

Router(config)#interface Serial0/1/0

Router(config-if)#ip address 192.168.1.1 255.255.255.0

Router(config-if)#ip address 192.168.1.1 255.255.255.0

Router(config-if)#no shutdown

Similarly for router 2 as per the given iage below.

Opsf configuration step:

To configure OSPF routing protocol on the above-mentioned topology, you need to perform the following steps.

Router(config)#router ospf <process id 1-65535>

Router(config-router)network <network address> <wild card mask> area <0-4294967295>

1.    Move on to Router1 and execute the following commands to specify the OSPF network and area.

2.    Router1(config)#router ospf 200

3.    Router1(config-router)#network 10.0.0.0 0.255.255.255 area 0

4.    Router1(config-router)#network 192.168.1.0 0.0.0.255 area 0.0.0.0

Router1(config-router)#exit

 Similary for router 2 has to be done .
