Step 1: Select the port interfaces which will be plugged in and set them equal to their respective and set their port interfaces = to the default gateway. Examples: East Router FA0/0 = IP address 10.17.1.21.

Step 2: Confirm each interface is set to no shut

Step 3: Configure OSPF using the NET ID and the reversed Subnet mask: Example - Network 10.17.1.21 0.0.0.7 area 0

The original cabling is not correctly done in the original packet tracer file. As such confirm that the correct ether/fa port is connected to each machine. This can be done by hovering over the connector.

In the table where it lists the Network address. The first address should be set on the main device. For instance where it says "East-Router2 to DC" the East router IP should be 10.17.1.21 while the DC address for the connected port should be 10.7.1.22

Setting up OSPF on west router requires the network address of the systems on the west router 10.7.40.0/24 and that of the DC 10.7.32 /30. The command syntax would be the same as what is used on the DC server
