OSPF Routing Configuration

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

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 192.168.2.0 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
