Objectives Part 1: Examine Network Requirements Part 2: Design the VLSM Address Scheme Background / Scenario Variable Length Subnet Mask (VLSM) was designed to avoid wasting IP addresses. With VLSM, a network is subnetted and then re-subnetted. This process can be repeated multiple times to create subnets of various sizes based on the number of hosts required in each subnet. Effective use of VLSM requires address planning, In this lab, use the 192.168.21.0/24 network address to develop an address scheme for the network displayed in the topology diagram. VLSM is used to meet the IPv4 addressing requirements. Part 2: Examine Network Requirements In Part 1, you will examine the network requirements to develop a VLSM address scheme for the network displayed in the topology diagram using the 192.168.21.0/24 network address. Step 1: Determine how many host addresses and subnets are available. How many host addresses are available in a 24 network? What is the total number of host addresses needed in the topology diagram? How many subnets are needed in the network topology? Step 2: Determine the largest subnet. How many IP addresses are required in the largest subnet? What subnet mask can support that many host addresses? How many total host addresses can that subnet mask support? Can you subnet the 192.168.21.0/24 network address to support this subnet? What are the two network addresses that would result from this subnetting? Use the first network address for this subnet. Step 3: Determine the second largest subnet. What is the subnet description? How many IP addresses are required for the second largest subnet? What subnet mask can support that many host addresses? How many total host addresses can that subnet mask support? Can you subnet the remaining subnet again and still support this subnet? What are the two network addresses that would result from this subnetting? Use the first network address for this subnet. Step 4: Determine the subnets needed to support the serial links. How many host addresses are required for the serial subnet link? What subnet mask can support that many host addresses? a. Continue subnetting the first subnet of each new subnet until you have four /30 subnets. Write the first two network addresses of these /30 subnets below. Part 2B: Design the VLSM Address Scheme Step 5: Calculate the subnet information. Use the information that you obtained in Part I to fill in the following table. First Host Address Last Host Address Broadcast Address Number of Network Subnet Hosts Address Description Needed ICIDR Doha LAN 100 GOO Muscat LAN 60 GOO Doha S0/0/0 Muscat S0/0/1 2 Step 6: Complete the device interface address table. Device Interface IP Address Subnet Mask Device Interface GOO 100 Host LAN Doha S000 Muscat S0011 GO/ 60 Host LAN Muscat SO/0/1 Doha S000 Assign the first host address in the subnet to the Ethernet interfaces. HQ should be given the first host address on the Serial links to BRI and BR2. BRI should be given the first host address for the serial link to BR2. Reflection Can you think of a shortcut for calculating the network addresses of consecutive /30 subnets Step by Step Solution
