IP Subnetting and Router Configuration for Network Implementation

This assignment provides a detailed solution for IP subnetting, starting with a network address of 192.168.45.0/24, which is then divided into eight subnets, each with 62 hosts. The solution includes the network address, subnet mask, broadcast address, and valid host address ranges for each subnet. It then moves on to the IP routing configuration, detailing the network implementation for four networks (NET-A, NET-B, NET-C, NET-D) and the subnets connecting the routers (RA-RB, RA-RC, RB-RC, RC-RD). The assignment includes IP addresses and subnet masks for PCs and router ports, along with the router configurations for RA, RB, RC, and RD, using RIP routing protocol. The configuration for each router includes interface settings, IP address assignments, and RIP routing setup. Finally, the assignment concludes with a routing table and testing phase, where ping tests are performed between PCs in different networks to verify the functionality of the network implementation.
