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.

Instructions:

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

Device Interface IP Address Mask
R1 S0
S1
192.168.1.1
192.168.3.1
255.255.255.0
255.255.255.0
R2 S0
S1
192.168.1.2
192.168.2.1
255.255.255.0
255.255.255.0
R3 S0
S1
192.168.3.2
192.168.2.2
255.255.255.0
255.255.255.0

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 a ping and trace command to R2-S1 and R3-S1 interfaces

On R1:

R1>enable
R1#configure terminal
R1(config)#interface serial 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 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
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 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
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 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 : 

Description: The purpose of this exercise 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. 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 interface and click edit button
4. Configure the IP address as 192.168.1.1 255.255.255.0 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.
8. Select device R2 from Select Device drop down box.
9. Repeat steps 2 7 for configuring R2 S0 interface ip address as 192.168.1.2 255.255.255.0 , S1 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 interface ip address as 192.168.3.2 255.255.255.0 , S1 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-S1 and R3-S1 interfaces and check the connectivity
