OSPF PT Activity

Purpose:

• In this lab we learn how to configure and implement OSPF onto a Small Enterprise Environment in order to allow internal networks to be dynamically routed using the Shortest Path First (SFP) algorithm.

Materials:

• Cisco Packet Tracer
• Lab Packet Tracer File

Objective:

The completed lab environment should look similar to below:

Additionally, I used the following Routing Table to help configure the Network Environment above:

Network Name	Network Address	Subnet Mask	Default Gateway	Router acting as Gateway
Border-to-Data Center	10.6.1.0	255.255.255.248	10.6.1.1	Border
East-Router2 to Data Center	10.6.1.20	255.255.255.252	10.6.1.21	East-Router
DataCenter-to WestRouter4	10.6.1.32	255.255.255.252	10.6.1.33	Data Center-Router
East	10.6.20.0	255.255.255.0	10.6.20.1	East-Router
West	10.6.40.0	255.255.255.0	10.6.40.1	West-Router

Deliverables:

Deliverable 1:

Figure 1: Screenshot of me successfully pinging between the East PC (10.6.20.2) using the West PC (10.6.40.2)

Deliverable 2:

Figures 2.1 + 2.2 + 2.3 + 2.4: Screenshots of the output of the “sh ip route” command being run on the Border, Datacenter, East, and West Routers. This shows that each network has been successfully added to each router’s routing table via OSPF.
