TI 5.1.6 – Repeaters

Objective:

- Create a simulated network topology
- Apply IP addresses to workstations
- Be familiar with the function of a repeater
- Understand the Four Repeater Rule
- Test the simulated topology

Step 1

Create the topology shown in the diagram in Packet Tracer. After connecting all the devices, assign each PC with a valid IP address and subnet mask. (You can use any IP addresses as long as they belong to the same network.)

Step 2

a) Click on the Simulation tab to start creating a scenario.

b) Add a packet and click on source PC 0 and then click on destination PC 1. Add another packet from PC 1 to PC 2.

c) Click play to watch the simulation.

d) Take note of the time it takes for each packet to reach its destination. (Having more repeaters between workstations adds latency to the packets.)

Step 3

a) Click once on the arrow on the left of the play button to go back one second (The number in the Time box should be “6”)

b) Add a packet from PC 2 to PC 1.

c) Click on the Topology tab. Remove a connection then add another repeater anywhere between Switch 0 and PC 2. Re-connect the devices.

d) Click on the Simulation and hit the play button to watch the simulation. (Latency results in collision.)
