Learn the basics for Packet Tracer before you start to complete Assignment 1.

Question 1: (60 marks)

Using Packet Tracer 8.0.1, implement the following network:

When implementing networks, some suggestions:

• Device naming scheme
  • Network (LAN) name is A
  • PC names are PCA1, PCA2 etc.
  • LAN Switch names are SA1 etc.
  • Gateway Router names are RA1 etc.
• Links between devices
  • All PCs linked to switch(es)
    • straight through cable.
    • usually ethernet or fast ethernet link.
    • can be but rarely linked directly to router using cross-over cables.
  • All switches linked to PCs and (gateway) router (gateway, usually one) usually using gigabit links.
• (IP) addressing scheme
  • Network address e.g. 192.168.1.0 /24 (first address)
  • Broadcast address e.g. 192.168.1.255/24 (last address)
  • The first (or first few) or last (or last few) available address(es) for devices are usually assigned to the Gateway.
    • e.g. 192.168.1.1 to gateway or
    • e.g. 192.168.1.254 to gateway
  • We use the last available address for the gateway router in this question.
  • Switch addresses (not needed in most cases)
  • PC (and other devices) addresses – any address other than the first (for the network) or the last (for broadcasting within the LAN) or addresses already assigned.
    • e.g. 192.168.1.2/24
    • e.g. 192.168.1.37/24
    • e.g. 192.168.1.253/24
• RA – Model 2901 or another model.
• S2 – Model 2960 or another model.

For Q1:

• Network name: FN which is short for FirstNet
• Address scheme:
  • Network address – 192.168.1.0 /24
  • Broadcast address – 192.168.1.255/24
  • Router (gateway) addresses – 192.168.1.254
  • Switch addresses (not needed in Q1)
  • PC addresses – 192.168.1.1 and 192.168.1.2
• Switch port – Use FastEthernet ports for PC links and GigabitEthernet for gateway link.

Check that all PCs and routers can ping each other.

Submit your answer to Question 1 as <studentIDQ1>.pkt (e.g. U123456Q1.pkt)

Question 2: (10 marks)

Based on the work for Q1, design the IP scheme for a company network with 100 PCs.

• Suggest an acceptable way to show the network diagram.
• Suggest an acceptable way to implement the network using Packet Tracer
• Suggest an acceptable way to implement the network using real PCs, switches, and routers.

Submit your answer to Question 2 as <studentIDQ2>.pdf (e.g. U123456Q2.pdf)

Question 3: (15 marks)

Based on Q1, if the company has 300 employees, suggest 3 different addressing schemes. Using diagrams similar to the one in Q1, show the possible IP addresses used in each scheme may look like. You have to specify the addresses used in each device.

Submit your answer to Question 3 as <studentIDQ3>.pdf (e.g. U123456Q3.pdf)

Question 4 (15 marks)

In Q1, we may join the PCs directly to the router. Discuss why this is not a common practice.

What is the common practice of linking a PC to a router? Why is this practice better?

Submit your answer to Question 4 as <studentIDQ4>.pdf (e.g. U123456Q4.pdf).
