OSPF Routing Configuration - Scenario

Console Based  |  GUI Based 

Console Based :

Description: The purpose of this Lab is to configure OSPF on all the devices and test for ping and trace commands.

The router ospf 1 command given in the lab below selects OSPF as the routing protocol.

Instructions:

1) Assign the IP address of all the devices as given below

2. Bring all the interfaces to up

3. Configure OSPF on all the Devices, Use Process ID 1 and Autonomous System number 0

4. From R1 issue ping and trace commands to R2-S0/1 and R3-S0/1 interfaces and check the connectivity

On R1:

R1>enable
R1#configure terminal
R1(config)#interface serial 0/0
R1(config-if)#ip address 192.168.1.1 255.255.255.0
R1(config-if)# no shutdown
R1(config-if)#exit
R1(config)#interface serial 0/1
R1(config-if)#ip address 192.168.3.1 255.255.255.0
R1(config-if)# no shutdown
R1(config-if)#exit
R1(config)#router ospf 1
R1(config-router)#network 192.168.1.0 0.0.0.255 area 0
R1(config-router)#network 192.168.3.0 0.0.0.255 area 0

On R2:

R2>enable
R2#configure terminal
R2(config)#interface serial 0/0
R2(config-if)#ip address 192.168.1.2 255.255.255.0
R2(config-if)# no shutdown
R2(config-if)#exit
R2(config)#interface serial 0/1
R2(config-if)#ip address 192.168.2.1 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#exit
R2(config)#router ospf 1
R2(config-router)#network 192.168.1.0 0.0.0.255 area 0
R2(config-router)#network 192.168.2.0 0.0.0.255 area 0

On R3:

R3>enable
R3#configure terminal
R3(config)#interface serial 0/0
R3(config-if)#ip address 192.168.3.2 255.255.255.0
R3(config-if)# no shutdown
R3(config-if)#exit
R3(config)#interface serial 0/1
R3(config-if)#ip address 192.168.2.2 255.255.255.0
R3(config-if)#no shutdown
R3(config-if)#exit
R3(config)#router ospf 1
R3(config-router)#network 192.168.3.0 0.0.0.255 area 0
R3(config-router)#network 192.168.2.0 0.0.0.255 area 0

On R1:

R1#ping 192.168.2.2
R1#ping 192.168.2.1
R1#trace 192.168.2.2
R1#trace 192.168.2.1

GUI Based :

Instructions:

1. Select R1 from Select Device drop down box.

2. Choose configure > Interface Management > Interface and Connections.

3. In Edit Interface connections tab select the S0/0 interface and click edit button

4. Configure the IP address as 192.168.1.1 255.255.255.0 and enable the interface status, also configure the s0/1 interface ip address as 192.168.3.1 255.255.255.0 and enable the interface status.

5. Choose Router > Dynamic Routing select OSPF from the protocol list and click Edit button.

6. In the Edit IP dynamic routing window enter OSPF process id 1 and click add button to add a network.

7. Enter 192.168.1.0 as network address , wildcard mask 0.0.0.255 and area 0 and click OK button , click add button again in Edit IP Dynamic Routing window and add the network 192.168.3.0 , wildcard mask 0.0.0.255 and area 0 in add a network window and click OK button.

8. Select device R2 from Select Device drop down box.

9. Repeat steps 2 – 7 for configuring R2 S0/0 interface ip address as 192.168.1.2 255.255.255.0 , S0/1 interface ip address as 192.168.2.1 255.255.255.0 and network addresses 192.168.1.0 ,192.168.2.0 , wildcard mask as 0.0.0.255 and area 0.

10. Select R3 from Select Device drop down box.

11. Repeat steps 2 – 7 for configuring R3 S0/0 interface ip address as 192.168.3.2 255.255.255.0 , S0/1 interface ip address as 192.168.2.2 255.255.255.0 and network addresses 192.168.3.0 ,192.168.2.0 , wildcard mask as 0.0.0.255 and area 0.

12. From R1 issue ping and trace commands to R2-S0/1 and R3-S0/1 interfaces and check the connectivity
