Data Communication and Networking Lab: Mid Term Assignment

This document contains a midterm assignment for a data communication and networking lab course. It includes 3 questions asking the student to: 1) Explain and configure a TFTP server to store router configurations, designing a network with one router and 5 switches connected to the TFTP server. 2) Design and implement VLANs between 5 switches, each with 10 VLANs, and configure and test pinging between VLANs on different switches. 3) Explain IP addressing and subnetting, and create at least 10 networks using the IP 187.3.2.4/23 in Packet Tracer, drawing the network diagram and configuring the router IP addresses.

Question # 1 (7)
Explain and configure TFTP server in storing the configuration of Router. You have to
design the one router connected with 5 switches and one TFTP Server in packet tracer.

TFTP Server

TFTP, or Trivial File Transfer Protocol, is a simple high-level protocol for transferring data
servers use to boot diskless workstations, X-terminals, and routers by using User Data
Protocol (UDP).Although it may sound similar, TFTP works differently than FTP (File
Transfer Protocol) and HTTP (Hypertext Transfer Protocol). Although TFTP is also based
in FTP technology, TFTP is an entirely different protocol. Among the differences is that
TFTP’s transport protocol uses UDP which is not secure while FTP uses Transmission
Control Protocol (TCP) to secure information.

Question # 3(7)
What is IP addressing in networking. Why we need subnetting in IP addressing. Suppose
you have IP of 187.3.2.4/23. create at least 10 networks using router, switches in packet
tracer according to this IP.
IP addressing

An IP address (internet protocol address) is a numerical representation that uniquely


identifies a specific interface on the network. IP stands for Internet Protocol and describes
a set of standards and requirements for creating and transmitting data packets, or
datagrams, across networks. The Internet Protocol (IP) is part of the Internet layer of the
Internet protocol suite. In the OSI model, IP would be considered part of the network layer.
An IP address is an address used in order to uniquely identify a device on an IP network.
The address is made up of 32 binary bits, which can be divisible into a network portion
and host portion with the help of a subnet mask.

Subnetting

Subnetting allows you to create multiple logical networks that exist within a single Class
A, B, or C network. If you do not subnet, you are only able to use one network from your
Class A, B, or C network, which is unrealistic. Each data link on a network must have a
unique network ID, with every node on that link being a member of the same network. If
you break a major network (Class A, B, or C) into smaller subnetworks, it allows you to
create a network of interconnecting subnetworks. Each data link on this network would
then have a unique network/subnetwork ID. Any device, or gateway, that connects n
networks/subnetworks has n distinct IP addresses, one for each network / subnetwork
that it interconnects.
