Data Communication & Computer Networks Data Communication & Computer Networks : Instructor: Shahzad Malik/Suffian Shiekh/ Zafar Hadier Lab Coordinator: Shoieb Arshad LAB No. 4 Introduction to Variable Length Subnet Masking (VLSM) Purpose: The lab is intended to familiarize the students with a networking technique of Variable Length Subnet Masking (VLSM). At the end of the lab the student must know: • The Purpose of VLSM. • Steps of VLSM. • How to perform VLSM on different IP Classes. • Calculating the ranges of Hosts in the VLSM. • Finding the Broadcast address of the VLSM. • How to Broadcast on that VLSM. prompt> ifconfig <interfaceNo> xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx prompt> ifconfig eth0 netmask prompt> ping -b <broadcast_ip> VLSM: A Variable Length Subnet Mask (VLSM) is a means of allocating IP addressing

Unformatted text preview: resources to subnets according to their individual need rather than some general network-wide rule. The purpose of VLSM is use given IP we can make a network which can fulfill the requirements of an organization. E.g. If the Given IP is: and we are given with the following tree STRUCTURE of the organization: 1 | P a g e Data Communication & Computer Networks THEREFORE THE SUBNETS ARE: A1: A2: A3: A4: Now from A2: B1: B2: B3: Now from B3 C1: C2: C3: C4: Now from C3 D1: D2: Task 1: Perform the Technique on this Organization tree. And find the Subnets Task 2: Implement the structure in packet tracer. 2 | P a g e...
