a) Each router will of course have an end device connected with it and a switch in-between. Test the passing of your packets from one router to another. Configure the following networks using the Cisco-Packet tracer. b) Now connect all your routers with each other in the given scenario. Then also test and show the accurate static routing using the mentioned path. Make sure the entire network runs as you intended. The IP address of devices, as well as the routes using specific connections, can be given according to your own liking. c) Now add 3 different mail servers namely cse.green.edu.bd, eee.green.edu.bd, tex.green.edu.bd, under router 1, 2 & 3 respectively. Also, add one FTP server at router 4 and add the end devices under these four routers in this scenario. You can add DNS servers as your necessity. [All the devices should have an IP address range X.0.0.0 to X.255.255.255. Here X = (YourID) % 315+ 1] Router 2 Router 1 Router 4 Router 3
