Creating a Small Network

The final exam for this course is a comprehensive lab activity. You may consult with other students on this lab if you wish, but each student should submit a separate lab that represents your own work. The lab must be submitted no later thanMonday, May 11 at 7 PM. Late submittals will not be accepted. Note that in this lab you will not have the ability to check results. You will see a percentage complete so you'll have some sense for when you are done, but you will not be able to see which items are being checked. Also, it is important that you realize the percentage complete is not your grade. You may be 63% complete and get a 90 on the lab, or you could be 92% complete and get a 70. The grading criteria are given in the lab directions, but as usual, you are working to establish full connectivity between all devices and interfaces. Enjoy, and good luck!

Topology

Overview

In this lab you will be building a small network, and your tasks will include subnetting, configuring routers, switches and PCs, creating VLANs, InterVLAN routing, static routing, and dynamic routing using OSPF. The grading for the lab is divided into four sections, as follows:

Network Design (15 points) - subnetting a /24 network
Basic Configuration Tasks (25 points) - includes configuring hostnames, interfaces, and default gateways
Configure the Branch LANs (25 points) - configuring switchports, VLANs, and InterVLAN routing
Configure Static and Dynamic Routing (35 points)Basic Configuration Tasks (25 points)

Configure the hostnames on all routers and switches, as shown in the topology

Configure the serial interfaces for Branch, Central, and HQ according to your addressing table, and verify point-to-point connectivity.

Configure the Central LAN (PC3, Switch S4 and Central Gi0/1) with the appropriate addresses and mask, and verify connectivity from the PC and the switch to the default gateway.

You will be configuring the interfaces in the Branch LAN in the next step.

Configure the Branch LANs (25 points)

From your addressing table, configure the appropriate IP address, subnet mask, and default gateway on PC1 and PC2.

Create VLANs 2 and 3 on all three switches, naming VLAN 2 Students and VLAN 3 Faculty. Configure ports fa0/5, fa0/6, and Gi0/1 as trunk ports on all three switches. On S2, configure port fa0/12 as an access port and assign it to VLAN 2. On S3, configure Fa0/13 as an access port and assign it to VLAN 3. These three switches will not be assigned an IP address.

On router Branch, configure interface Gi0/1 with subinterfaces to provide InterVLAN routing for VLANs 2 and 3. For both subnterfaces, assign the first assignable addresses in the network assigned to that VLAN, as indicated on your address table. Turn up the G0/1 physical interface. Verify PC1 and PC2 can ping their respective default gateways. Verify InterVLAN routing between PC1 and PC2

Configure Static and Dynamic Routing (35 points)

You will be configuring dynamic routing between HQ, Central, and Branch using OSPF. For each router, begin by entering router ospf configuration mode with process id 1, and assign OSPF router-ids as follows: Branch should be assigned 1.1.1.1. Central should be 2.2.2.2, and HQ should be 3.3.3.3.

Next, with the exception S0/0/0 on HQ, enable all interfaces on all routers in area 0 with the OSPF network command. The HQ S0/0/0 interface will not be enabled is OSPF since you will be doing static routing with the ISP. Use the correct wild card mask for each network (recall that the wildcard mask can be determined by subtracting the subnet mask from the 255.255.255.255. For example, a /30 network has a 255.255.255.252 network mask, and subtracting that from the 255.255.255.255 gives a wildcard mask of 0.0.0.3 for a /30 network). When you have correctly completed these tasks you should see OSPF routes in the routing tables, and OSPF adjacencies when you enter the show ip ospf neighbor command.

To complete the routing, you must configure two static routes. First, create a static default on HQ pointing to the ISP router (S0/0/0). Redistribute the static default to the OSPF domain with the OSPF configuration command default-information originate. Secondly, create a static route on the ISP router to the 172.16.3.0 /24 network, pointing to the S0/0/0 interface. If these are correctly configured, and your OSPF configuration is working, you should now have full connectivity between all hosts, servers, and router interfaces.

Verify correct operation

Before submitting, verify that all PCs can reach their default gateways and all the other PCs the Internet server. Note that your percentage complete may or may not show 100% - If you have competed all steps and have interconnectivity between all devices, you have completed the lab, and your grade will reflect that.

I suggest that you print out these directions for reference as you complete this activity. There are no embedded instructions in the lab itself.

Network Design

You will be creating the networks for the 3 customer LANs and the two internal Point-to-point networks. You are given the 10.10.1.0 /24 network to work with.

First create the Central LAN network, which will need to support 100 hosts. The second network will be the Student LAN (VLAN 2), and will need to support 60 hosts. The third network will be the Faculty LAN (VLAN 3), which will need to support 30 hosts. The fourth and fifth networks will be used for the two serial point-to-point links, and will each support 2 hosts. Note that there will be unused address space when you have completed your subnetting.

For the LANs, assign the first usable address to the router interface, and the second address to the PCs. For the Central LAN, you will also be assigning the last assignable address to S4 switch VLAN 1 interface. I strongly recommend that you fill out the following table to keep things straight. Since the % complete will depend on the correct subnetting and address assignments, you may want to confirm you have done this step correctly before proceeding. If you submit your subnetting diagram to me, I will grade it and correct it. That way you will know that part is correct, and you can focus on the configuration. There will be a separate submittal link for your subnetting table. Note that this submittal is not required, but it is recommended.
