Step 1: Connect the Devices

Step 2: Configure the Device Basics
Configure addressing on R2

R2(config)#int fa0/0
R2(config-if)#ip add 172.16.100.1 255.255.255.192
R2(config-if)#no shut

R2(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

R2(config-if)#exit
R2(config)#int fa0/1

R2(config-if)#ip add 172.16.100.118 255.255.255.248
R2(config-if)#no shut

R2(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up

R2(config-if)#exit
R2(config)#int s0/0/0
R2(config-if)#ip add 172.16.100.126 255.255.255.252
R2(config-if)#no shut

%LINK-5-CHANGED: Interface Serial0/0/0, changed state to up
R2(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0, changed state to up

R2(config-if)#exit
R2(config)#int loopback0

R2(config-if)#
%LINK-5-CHANGED: Interface Loopback0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up

R2(config-if)#ip add 10.0.0.2 255.255.255.255
R2(config-if)#no shut
R2(config-if)#exit
R2(config)#

Configure H3 IP address

IP Address            : 172.16.100.94
Subnet Mask        : 255.255.255.224
Default Gateway : 172.16.100.65

 Step 3: Configure OSPF.
Use the process ID 1

R1(config)#router ospf 1
R1(config-router)#network 172.16.100.120 0.0.0.3 area 0
R1(config-router)#network 172.16.100.64 0.0.0.31 area 0
R1(config-router)#network 172.16.100.112 0.0.0.7 area 0
