Configuring Multi-area OSPF using packet tracer

In this blog i have shared how i created this little OSPF multi-area learning project

I started by creating a layout of the network by using 4 routers and 3 switches

there are 3 areas with thier own ip addresses:

• area 0 = 10.10.10.8/30

• area 1 = 10.10.10.4/30

• area 2 = 10.10.10.0/30

then for the ip configuration on routers I have assigned the first ip address available of the network or area to the router 0, as in area 0 the network is 10.10.10.8/30 so the router interface in this network will have ip address of 10.10.10.9/30 and router 1 will have 10.10.10.10/30 respectively. same is done with other routers interfaces

Configure OSPF in all routers to advertise the directly connected routers

starting with the router 1. this router is connected to 2 networks and these networks are in area 0

I gave the router id of 1.1.1.1 as router name is router1

here i have to use a wild card subnet mask to enter the network

same has to be done with other routers with thier respective networks they are connected to within thier areas

now on router 0 configure all the networks with the respective area for that interface, as for router0 interface to router1 is in area0 so the command should be: network 10.10.10.8 0.0.0.3 area 0

with show ip ospf neighbor command we can see the ospf neighbors of router0

at last i have test this network by using the ping command from pc0 to pc2 and it works good
