Assignment: Network Layer
Question 1: Routing
1. Use the Packet Tracer software to build the above network.
a. Choose the generic empty router type for your routers.
b. Choose the generic empty switch type for your switches
c. Add the necessary Gigabit Ethernet interfaces for fiber optics media to connect routers together. Explain your choice of network modules.
d. For local area networks, use fast Ethernet interfaces for copper media. Explain your choice of network modules.
2. Assign IPv4 addresses using class C private addresses. Explain your choice of IPv4 addresses.
a. Assign static IPv4 addresses, subnet masks, and default gateways to the PCs interfaces.
b. Assign static IPv4 addresses to the routers interfaces.
You may include a table with the headers: Device, Interface, IP address, and Subnet mask.
3. Configure your router using static routing method. No dynamic routing should be used in this step. Discuss the network routes you added to each router. After testing your configuration using ping and tracert commands, save your network in a file named yourname_static.pkt.
4. Using the previous configured network (question 2), configure the routers using RIP as a dynamic routing protocol. Explain the entries added to each router. After testing your configuration, save your network in a file named yourname_dynamic.pkt.
5. Compare the routing tables of Router 2 obtained from the static (question 3) and dynamic (question 4) configurations. Explain each entry in the routing tables.
Deliverables:
- Static routing network file named yourname_static.pkt
- Dynamic routing network file named yourname_dynamic.pkt
- Network report document in docx or pdf formats.
Note: All configurations should be achieved using the Packet Tracer graphical user interface (the command line CLI is out of scope in this course).
Question 2: ICMP Protocol
1. Explain briefly the purpose of the ICMP protocol. At which layer the ICMP is located?
2. What is the general structure of the ICMP packet? Explain each field in the ICMP header.
3. Explain the following ICMP packet types. Provide the packet structures.
a. Type 0 Code 0
b. Type 8 code 0
c. Type 3 code 0
d. Type 11 Code 0
4. Discuss the functioning of the ping command and its default output without using any option.
5. Discuss the functioning of the tracert command and its default output without any option.
