CS407 - Routing and Switching

Re: CS407 Assignment 1 Solution and Discussion Assignment No. 01 Semester: Spring 2020 CS407: Routing and Switching Total Marks: 20 Due Date: 29 May 2020 Instructions: Please read the following instructions carefully before submitting assignment: You need to use MS word document to prepare and submit the assignment on VU-LMS. It should be clear that your assignment will not get any credit if:  The assignment is submitted after due date.  The assignment is not in the required format (doc or docx).  The submitted assignment does not open or file is corrupt.  Assignment is copied (partial or full) from any source (websites, forums, students, etc). Objectives: To enhance the learning capabilities of students about:  Basics of networks  OSI model  Types of networks  IOS modes of operations  Verifying network connectivity  CLI access methods Assignment Scenario: Consider the computer network of a software house “TECH-REPUBLIC” having two branches as branch 1 and 2. These branches are situated in two different cities and are connected with each other as per following details: • Branch-1 has twenty computers and two servers which are connected with each other using a Switch. • Branch-2 has ten computers and one server which are connected with each other using a Switch. • Switches of both the branches are further connected with one Router in their premises to connect both the branches with each other for internet communication. The CEO of the software house from Branch-1 wants to address his staff located in Branch-2 through video conferencing in upcoming week. However, due to malfunctioning of Switch in Branch-2, the concerned network administrator (Admin) of that branch has to install a new switch prior to conference day/date. Furthermore, the router of Branch-2 is also required to be accessed by the Admin of Branch-1 to perform some important configurations remotely to make the communication smooth. In view of the above scenario, you are required to give answers of the following questions: What is the type of computer network in Branch-1 with respect to geographical area? What is the type of computer network in Branch-2 with respect to geographical area? What is the type of overall computer network of software house with respect to geographical area? How many intermediary devices exist in the Branch-2 premises? How many end devices exist in overall network of the software house? Which specific layer of OSI model will make the Routers of two branches to communicate with each other? What access mode of command line interface (CLI) of a switch will be more suitable for the Admin of Branch-2 to configure the initial settings of the Switch? What operational mode, the Admin will have to use to enter management commands on the Switch? Which command will be used by the Admin to verify the connectivity of a computer with the Switch? What access mode of command line interface will be more suitable to perform remote configurations on the router in secure manners? Good Luck!

Assignment No. 03 Semester: Fall 2019 CS407: Routing and Switching Total Marks: 25 Due Date: 30 Jan 2020 Please read the following instructions carefully before submitting assignment: You need to use Packet Tracer to prepare the assignment in .pkt file format. It should be clear that your assignment will not get any credit if:  The assignment is submitted after due date.  The assignment does not contain (.pkt) file.  The submitted assignment does not open or file is corrupt.  Assignment is copied (partial or full) from any source (websites, forums, students, etc.) Objectives: To enhance the hands-on training on Packet Tracer tool for: • Designing Network Topology • Setting IPv4 addresses on the devices • Labeling Devices • Configuring Host Name on Router • Configuring Router Interfaces • Creating and Implementing Access List on Router • Accessing devices and server on a network to verify the connectivity Assignment You are required to perform following Tasks using Packet Tracer Tool: Task 1: Designing Network Topology: Design a network topology of two local area networks (LAN A and LAN B) connected with each other through a router titled /labeled as Main Router. LAN A is comprised of three computers titled / labeled as “Admin”, “User A” and “User B” respectively which are connected with each other through a Switch titled /labeled as Switch A. In LAN B, just a server titled /labeled as “Data Server” is connected to a switch titled / labeled as Switch B. You need to connect all the devices with each other using appropriate cables and interfaces. All links among all devices must be up. Take Screen Shot after designing the topology. Task 2: Configuring IP addresses: Assign IP addresses and default gateways to all computers and server respectively as per following scheme: Machines IP addresses Default Gateway Computers (Admin, User A and User B) 120.110.10.3 120.110.10.1 120.110.10.2 120.110.10.1 120.110.10.4 120.110.10.1 Server (Data Server) 192.30.40.3 192.30.40.1 Task 3: Accessing devices and Verifying Connectivity: • Check the connectivity among devices by applying related commands in command prompt. Take Screen shot of this activity for verifying the connectivity between the computer “User A” and “Data Server”. Task 4: Configuring Host Name: • Configure host name of router as your VUID by applying proper commands. Take Screen shot of all commands entered in command line interface after completing this task. Task 5: Restricting access of device: • By creating and implementing Standard Access List on relevant router, block the traffic from the computer “User A” towards the “Data Server”. • You need to give access list number as the last two digits of your VUID except 00. If a student has last two digits as 00 in his /her ID, then he /she need to give number as 99. • Write appropriate commands to show the access list implemented on the router. Take Screen shot of all commands entered in command line interface after completing this task. Task 6: Verifying the Access List: • By writing related commands in the command prompt check the reachability of the computer “User A” to the “Data Server”. Take Screen shot of all commands entered in command line interface after completing this task. After completing all these activities on Packet Tracer, you need to save as the file with your “VUID.pkt”. Paste all the screen shots as required in different above-mentioned tasks in MS Word file. Save as the file with your VUID.docx”. Put .Pkt and MS Word files in one folder, ZIP the folder and submit on VU-LMS within due date. Good Luck!
