LAB 2-3: Spanning Tree Protocol (STP)

You are the Network Administrator of Ranet, and
would like:
- Ranet-CoreSW to be the Root Bridge
- Port Fa0/2 of Ranet-SW2 to be in the blocking state
Please config spanning-tree parameter on both
Ranet-CoreSW and Ranet-SW2 via its console to be
as the requirement above.

Remark: Use command to set priority as lowest/highest
as possible to gain the point (%Completion) for this
question.

LAB 2-2: Virtual Trunking Protocol (VTP) 


You are the Network Administration at Ranet, and have to config to let Ranet-SW3 seperate VLAN
according to the VLAN database from Ranet-SW1 via VTP (use Console for each switch) as below:

1. Gather information about VTP configuration in Ranet-SW1 by using "show" command in
USER mode only. (You do not have right to config anything on this switch.)

2. On switch Ranet-SW2, you have to config to let the VTP information send from Ranet-SW1
via itself to Ranet-SW3 without any change in VLAN database of Ranet-SW2

3. On switch Ranet-SW3, you have to config to receive VTP information from Ranet-SW1 and
use the received VLAN database to set members of each VLAN as:
VLAN 10: Fa0/1
VLAN 20: Fa0/2

LAB 2-1: InterVLAN Routing 

You are the Network Administrator at Ranet, and have to config both switch "Ranet-SW" and router 
"Ranet-GW" via its console terminal as below: 

1. Set Ranet-SW to seperate VLAN to be VLAN 10 and VLAN 20 and set its member as: 
VLAN 10: Fa0/1, Fa0/2 
VLAN 20: Fa0/3, Fa0/4 

2. Enable feature "Portfast" on all access ports. 

3. Set both Ranet-SW and Ranet-GW to route between VLAN 10 and VLAN 20: 

- Use interface Fa0/0.1 and Fa0/0.2 on Ranet-GW as sub-interface for VLAN 10 and 
VLAN 20 respectively.
- Please note that all hosts in each VLAN set IP Default Gateway to be the last IP of its 
own subnet. 

If everything is correct, All hosts will be able to connect with each other.
