VTP Lab
Question:
The headquarter offices for a book retailer are enhancing their wiring closets with Layer3 switches. The new distribution-layer switch has been installed and a new access-layer switch cabled to it. Your task is to configure VTP to share VLAN information from the distribution-layer switch to the access-layer devices. Then, it is necessary to configure interVLAN routing on the distribution layer switch to route traffic between the different VLANs that are configured on the access-layer switches; however, it is not necessary for you to make the specific VLAN port assignments on the access-layer switches. Also, because VLAN database mode is being deprecated by Cisco, all VLAN and VTP configurations are to be completed in the global configuration mode. Please reference the following table for the VTP and VLAN information to be configured:

Requirements:
| VTP Domain name | cisco | |
| VLAN Ids | 20 | 21 |
| IP Addresses | 172.16.71.1/24 | 172.16.132.1/24 |
These are your specific tasks:
1. Configure the VTP information with the distribution layer switch as the VTP server
2. Configure the VTP information with the access layer switch as a VTP client
3. Configure VLANs on the distribution layer switch
4. Configure inter-VLAN routing on the distribution layer switch
5. Specific VLAN port assignments will be made as users are added to the access layer switches in the future.
6. All VLANs and VTP configurations are to completed in the global configuration. To configure the switch click on the host icon that is connected to the switch be way of a serial console cable.
Answer and Explanation:
1) Configure the VTP information with the distribution layer switch as the VTP server:
DLSwitch#configure terminal
DLSwitch(config)#vtp mode server
DLSwitch(config)#vtp domain cisco (use cisco, not CISCO because it is case sensitive)
(Requirement 2 will be solved later)
3) Configure VLANs on the distribution layer switch
To create VLANs on a switch, use the vlan vlanID# command:
DLSwitch(config)#vlan 20
DLSwitch(config)#vlan 21
Configure Ip addresses for Vlans:
DLSwitch(config)#interface vlan 20
DLSwitch(if-config)#ip address 172.16.71.1 255.255.255.0
DLSwitch(if-config)#no shutdown
DLSwitch(if-config)#interface vlan 21
DLSwitch(if-config)#ip address 172.16.132.1 255.255.255.0
DLSwitch(if-config)#no shutdown
DLSwitch(if-config)#exit
4) Configure inter-VLAN routing on the distribution layer switch
DLSwitch(config)#ip routing
DLSwitch(config)#exit
DLSwitch#copy running-config startup-config
2) Configure the VTP information with the access layer switch as a VTP client
ALSwitch#configure terminal
ALSwitch(config)#vtp mode client
ALSwitch(config)#vtp domain cisco
ALSwitch(config)#exit
ALSwitch#copy running-config startup-config
(Notice: Many reports said the copy running-config startup-config didn’t work but they still got the full mark)

Hey would someone mind sending me this the packet tracer file for this lab? Thanks! mattc514@gmail.com

Someone?
Can provide a valid links to download all SIMs please…
Hi Guys! Am using GNS3 for my Routing exam and will be going shortly for the Switching. Can anyone send ( tell) what to use since GNS3 doesn’t support switch. Kind regards. My emai: nissy357@yahoo.com
Silas, only way is to buy real switches. I bought two 2960′s on ebay for $100 each, and a 2621XM for $75. Additionally I got a 3560 layer 3 switch for near $300.
You can use Packet Tracer for some stuff, but not everything.
Hi, There are lots of MCQ questions that are in the certprepare but not included in the latest dump. Are those questions no more included in the exam???
Does anyone have the Packet Tracer files for this
@all – it takes about 10 mins to created this lab in the Packet Tracer. Try to created it yourself, it will give you an added value
I think the link between the DLswitch and ALSwitch ve to be trunk before VTP advertisement can be exchanged.
I could not understand it , because there is no configuration done in solution.
5. Specific VLAN port assignments will be made as users are added to the access layer switches in the future.
@Irfan, there is no configuration to be done. It’s just letting us know that for now we don’t need to configure any access port vlans.
I have made a simple lab particularly for this simulation. Its pretty straight forward. I’m currently preparing to write my switching exam 642-813 on the 12 April 2013. I hope this might help someone in need. Thanks and all the best to whoever will be writing the switching exam. here is the link http://www.4shared.com/account/dir/_fio_8cm/_online.html#dir=_fio_8cm
my bet here is the proper link http://www.4shared.com/file/E6BH8nwR/VTP_Lab.html
@Kolop – you are correct. Interface fa0/1 on BOTH sides need to be configured as trunks.
@jakymix Does not work with v5 of packet tracer
I’ve done this lab on V5.3.3.0019. It should work trust me.
DLSwitch#show run
Building configuration…
hostname DLSwitch
ip routing
spanning-tree mode pvst
interface FastEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
interface Vlan20
ip address 172.16.71.1 255.255.255.0
interface Vlan21
ip address 172.16.132.1 255.255.255.0
end
ALSwitch#show run
hostname ALSwitch
spanning-tree mode pvst
interface FastEthernet0/1
switchport mode trunk
end
configure interfaces as trunk for VTP to work – missed in the config above
@Anonymous You technically don’t need to trunk interface FastEthernet0/1 on either device as the default mode for a port is dynamic desirable and will automatically form a trunk, unless of course the default config has changed.
I am planning to give switching exam, can one provide valid Switching dumps please.. Email : ece124@gmail.com
Thanks in Advance
Dear all,
If anybody wants this lab, or packet tracer latest version. please mail me on my mail id… my id is…. zubairy77@yahoo.com i will send him/her proper link of packet tracer and will send VTP MAIL.
You can also add me for further help.
thanks.
i need image files of Switches for GNS3 lab preparation. can any one help on it and also if provide images other than routers also helpful for me(virtual host,firewall and so on). Please mail me the images to dineshkumar.b.e.e.e@gmail.com
this lab is not in the exam

Hi,
@certprepare, @ ghost thanks u all
@all
In vtp lab 1,
I think ghost left some command, to think ourselves to work this lab correctly.
Even we configure like this, it will not work because although both switches are set to server and client, they did not synchronize vtp information.
Because we should check status of trunk interfaces which is connected between switches by using “sh int trunk” command.
You will see nothing on both switches on upper downloaded link pkt file.
Moreover, we will not complete without adding switchport to their respective vlan and making them switchport mode access.
You will not see this in question but you can see this question on the picture.
Even if the question did not state that we should check this by using
“sh vlan” command.
Here is complete command on both switches and work very well.
Use thes command on both switches to check status
“sh vlan”, “sh vtp status”, “sh interfaces trunk”
We are now start to configure
DLSwitch#conf t
DLSwitch(config)#vtp mode server
DLSwitch (config)#vtp domain cisco
DLSwitch (config)#vlan 20
DLSwitch (config-vlan)#ex
DLSwitch (config)#vlan 21
DLSwitch (config-vlan)#ex
DLSwitch (config)#int vlan 20
DLSwitch (config-if)#no shut
DLSwitch (config-if)#ip address 172.16.71.1 255.255.255.0
DLSwitch (config-if)#ex
DLSwitch (config)#int vlan 21
DLSwitch (config-if)#no shut
DLSwitch (config-if)#ip address 172.16.132.1 255.255.255.0
DLSwitch (config-if)#ex
DLSwitch (config)#ip routing
DLSwitch (config)#int fa 0/1(cable between two switches )
DLSwitch (config-if)#no shut
DLSwitch (config-if)#no switchport mode access
DLSwitch (config-if)#switchport trunk encapsulation dpt1q
DLSwitch (config-if)#switchport mode trunk
DLSwitch(config)#copy running-config startup-config
ALSwitch#conf t
ALSwitch(config)#vtp mode client
ALSwitch(config)#vtp domain cisco
ALSwitch(config)#int fa 0/2
ALSwitch(config-if)#switchport mode access
ALSwitch(config-if)#switchport access vlan 20
ALSwitch(config-if)#exit
ALSwitch(config)#int fa 0/3
ALSwitch(config-if)#switchport mode access
ALSwitch(config-if)#switchport access vlan 21
ALSwitch(config-if)#exit
ALSwitch(config)#copy running-config startup-config
Now you can ping between two pcs which will make u a complete lab.
// we don’t need to configure switchport trunk on ALSwitch because it is automatically trunk auto mode. They will negotiate themselves.
I hope this will helpful for u all, good luck in networking environment.
Moreover my command are here because of certprepare website and ghost’s labs. Thanks u too.
Hi
@theghibha,
If your p4sure is the latest one please it to me lawkanat28@gmail.com.
If not don’t send it to me because I have an old one.
Thanks u so much.
make sure interface fa0/1 of ALSwitch is in trunk mode otherwise VTP wont work or update.
#conf t
#int fa0/1
#switchport mode trunk
#end
@theghibha,
Thanks u so much for sending me!
Hi all,
When you complete this lab and execute a “show vlan” on the access layer switch should it not contain VLANs 20 & 21?
“show vtp status” still shows a revision number of 0 on my client even though the server is rev 4, any ideas?
^ Might be answering my own question here but i think you just need to change the interfaces to trunk mode
@Mojo
I have already mention about it.
Yes this is because there is no trunk between switch.
Plz see my explanation above.
