Question 4 (12 marks)

The network topology of USQCollege is shown below.

All links are of the same cost. STP is running.

L1 links S1 and S2 L2 links S2 and S3 L3 links S3 and S4 L4 links S4 and S5 L5 links S5 and S1

A green dot means the port forwarding and an orange dot means the port is in STP blocking state.

a) From the diagram, which switch is the root switch?

b) If switch S1 has a MAC address of 55:55:55:55:55:55, what can you say about the “value” of the MAC addresses of the other 4 switches?

c) Fill in the following table. You can consider a root port is also a designated port. To uniquely identify a port, you have to specify the port and the switch. The first line has been completed for you as an example.

Question 5 (20 marks)

ANZCollege also has three campuses and each campus runs its own LANs:

Toowoomba – 200.200.11.0/24 and 200.200.12.0/24 LANs Springfield – 200.200.21.0/24 and 200.200.22.0/24 LANs Ipswich – 200.200.31.0/24 and 200.200.32.0/24 LANs

The gateways for each campus are running OSPF.

The network administrator decided to link the three campuses together using Frame Relay.

From Toowoomba to Springfield using DLCI 102, network 200.8.12.0/29 From Springfield to Toowoomba using DLCI 201, network 200.8.12.0/29 From Toowoomba to Ipswich using DLCI 103, network 200.8.13.0/29

From Ipswich to Toowoomba using DLCI 301, network 200.8.13.0/29 From Springfield to Ipswich using DLCI 203, network 200.8.21.0/29 From Ipswich to Springfield using DLCI 302, network 200.8.21.0/29

Implement the ANZCollege network (6 LANs) using a Packet Tracer file.

Use router model 1941 Use switch model 2960

Use only 1 PC and a switch to represent all users in each LAN Design your own addressing scheme
