Objectives

In this lab you will design a VLSM addressing scheme given a network address and host requirements. You will configure addressing on routers, switches, and network hosts.

  • Design a VLSM IP addressing scheme given requirements.
  • Configure addressing on network devices and hosts.
  • Verify IP connectivity.
  • Troubleshoot connectivity issues as required.

Background / Scenario

You have been asked to design, implement, and test an addressing scheme for a customer. The customer has given you the network address that is suitable for the network, the topology, and the host requirements. You will implement and test your design.

Instructions

You have been given the network address [[DisplayNet]] by your customer. The host address requirements are:

Requirements

Host Requirements:

[[HostReg1]]

[[S2Name]] LAN

[[HostReg2]]

[[S3Name]] LAN

[[HostReg3]]

[[S4Name]] LAN

[[HostReg4]]

Design Requirements

  • Create the addressing design. Follow guidelines provided in the curriculum regarding the order of the subnets.
  • The subnets should be contiguous. There should be no unused address space between subnets.
  • Provide the most efficient subnet possible for the point-to-point link between the routers.
  • Document your design in a table such as the one below.

Configuration Requirements

Note: You will configure addressing on all devices and hosts in the network.

  • Assign the first usable IP addresses in the appropriate subnets to [[R1Name]] for the two LAN links and the WAN link.
  • Assign the first usable IP addresses in the appropriate subnets to [[R2Name]] for the two LANs links. Assign the last usable IP address for the WAN link.
  • Assign the second usable IP addresses in the appropriate subnets to the switches.
  • The switch management interface should be reachable from hosts on all of the LANs.
  • Assign the last usable IP addresses in the appropriate subnets to the hosts.

If the addressing design and implementation are correct, all hosts and devices should be reachable over the network.

Answers Notes:

The following addressing tables represent the three possible addressing scenarios the student may get. Note that the Device column is independent of the addressing scheme. For example, a student could receive the device names from Scenario 1 and the addressing scheme from Scenario 3. In addition, the three possible topologies are also independent of the device names and the addressing scheme (click reset in the activity to see the different topologies). Therefore, this activity uses three independent variables with three possible values each for a total of 27 possible combinations (3 device names x 3 addressing schemes x 3 topologies = 27 isomorphs).
