In This video I have done OSPF Multi Area configuration and i have also shown the various configuration step-by-step for easier and reliable configuration. I hope you will find this video informative and reliable to your needs. So here in this description also i have listed and mentioned the step-wise guidelines for easier configuration and understanding.
============================================================
We have the following configuration with 5 router in different different areas. The Router (R1) and R2 is in a Area 5. Router (R3) is in Area 10, Router (R5) is in Area 0 and Router (R4) is connected with Area 0, Area 5 and Area 10.
First of all we will configure the IP address on Router interfaces:
Configuring IP Address on Router Interfaces
R1
R1#configure terminal
R1(config)#interface Serial 0/1/0
R1(config-if)#ip address 10.0.0.2 255.0.0.0
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#int gig0/0
R1(config-if)#ip address 11.0.0.1 255.0.0.0
R1(config-if)#no shutdown
R1(config-if)#exit
R2
R2#configure terminal
R2(config)#interface Serial 0/1/0
R2(config-if)#ip add 20.0.0.2 255.0.0.0
R2(config-if)#no shutdown
R2(config-if)#exit
R2(config)#int gig0/0
R2(config-if)#ip address 21.0.0.1 255.0.0.0
R2(config-if)#no shutdown
R2(config-if)#exit
R3
R3#configure terminal
R3(config)#interface Serial 0/1/0
R3config-if)#ip address 30.0.0.2 255.0.0.0
R3(config-if)#no shutdown
R3(config-if)#exit
R3(config)#int gig0/0
R3(config-if)#ip add 31.0.0.1 255.0.0.0
R3(config-if)#no shutdown
R3(config-if)#exit
R3(config)#exit
R4
R4#configure terminal
R4(config)#interface Serial 0/1/1
R4(config-if)#ip address 10.0.0.1 255.0.0.0
R4(config-if)#no shutdown
R4(config-if)#clock rate 64000
R4(config-if)#exit
R4#configure terminal
R4(config)#interface Serial 0/0/0
R4(config-if)#ip address 20.0.0.1 255.0.0.0
R4(config-if)#no shutdown
R4(config-if)#clock rate 64000
R4(config-if)#exit
R4#configure terminal
R4(config)#interface Serial 0/0/1
R4(config-if)#ip address 30.0.0.1 255.0.0.0
R4(config-if)#no shutdown
R4(config-if)#clock rate 64000
R4(config-if)#exit
R4#configure terminal
R4(config)#interface Serial 0/1/0
R4(config-if)#ip address 40.0.0.1 255.0.0.0
R4(config-if)#no shutdown
R4(config-if)#clock rate 64000
R4(config-if)#exit
R5
R5#configure terminal
R5(config)#interface Serial 0/1/0
R5(config-if)#ip address 40.0.0.2 255.0.0.0
R5(config-if)#no shutdown
R5(config-if)#clock rate 64000
R5(config-if)#exit
R5(config)#int gig0/0
R5(config-if)#ip add 41.0.0.1 255.0.0.0
R5(config-if)#no shutdown
Now we will configure the OSPF Routing protocol on all routers
Configuring OSPF Routing Protocol with Multi Area.
R1 (Area 5)
R1#configure terminal
R1(config)#router ospf 1
R1(config-router)#network 10.0.0.0 255.0.0.0 area 5
R1(config-router)#network 11.0.0.0 255.0.0.0 area 5
R1(config-router)#exit
R1(config)#exit
R1#write
R2 (Area 5)
R2
R2#configure terminal
R2(config)#
R2 (config)#router ospf 1
R2(config-router)#network 20.0.0.0 255.0.0.0 area 5
R2(config-router)#network 21.0.0.0 255.0.0.0 area 5
R2(config-router)#exit
R2(config)#exit
R2#write
R3 (Area 10)
R3
R3#configure terminal
R3(config)#router ospf 1
R3(config-router)#network 30.0.0.0 255.0.0.0 area 10
R3(config-router)#network 31.0.0.0 255.0.0.0 area 10
R3(config-router)#exit
R3(config)#exit
R3#write
R4 (Area 0, 5, 10)
On Router R4 we are going to configure Area 0, Area 5 and Area 10 OSPF.
R4#
R4#config terminal
R4(config)#router ospf 1
R4(config-router)#network 10.0.0.0 255.0.0.0 area 5
R4(config-router)#network 11.0.0.0 255.0.0.0 area 5
R4(config-router)#network 20.0.0.0 255.0.0.0 area 5
R4(config-router)#network 21.0.0.0 255.0.0.0 area 5
R4(config-router)#network 30.0.0.0 255.0.0.0 area 10
R4(config-router)#network 31.0.0.0 255.0.0.0 area 10
R4(config-router)#network 40.0.0.0 255.0.0.0 area 0
R4(config-router)#network 41.0.0.0 255.0.0.0 area 0
R4(config-router)#exit
R4(config)#exit
R5 (Area 0)
R5#
R5#config terminal
R5(config)#router ospf 1
R5(config-router)#network 40.0.0.0 255.0.0.0 area 0
R5(config-router)#exit]
R5(config)#exit
R5#write
Now OSPF Routing Protocol is successfully configured on all routers.
OSPF Verifying Commands
Router#show ip route
Router#show ip route ospf
Router#show ip ospf
Router#show ip ospf interface
Router#show ip ospf neighbor detail
Router#show ip ospf database
In this video i have also done Ospf multi area configuration & verification from each routers along with it's hosts too for clear understanding. You can also check and verify connectivity, gitter, latency, delay and ping from source to destination. Thank You. Stay-updated for more updates and more videos coming ahead.
