COLLEGE OF SCIENCE AND ENGINEERING: IP Subnetting and Routing Project

This document provides a comprehensive solution to an IP subnetting and routing assignment for a Computer Networks course. The assignment involves designing and implementing a network with 8 subnets from a given network address, configuring IP routing using static or dynamic routing protocols, and implementing the network in Packet Tracer. The solution includes the sub-network information, IP address allocation for PCs and router ports, configuration scripts for each router, and ping verification screenshots to demonstrate network functionality. The goal is to ensure full network connectivity and demonstrate understanding of IP addressing, subnetting, and routing concepts.

Supplementary Assessment – Tri 2 - 2017
Objective:
 IP sub-netting and IP subnet design
 Perform basic IP routing
1 IP Sub-netting (30 marks)
Give a network address 192.168.xx.0/24 (Replace xx by the last 2 number of
your student ID. For example, if your student number is s012345678, then
replace xx by 78. Your network will be 192.168.78.0/24)
Perform IP sub-netting for the above given network address into 8 subnets
such that each subnet has the same number of IP Addresses.
Fill-in the sub-network information into the following table:
