        The particular goals for the actual lab will be spelled out in
the lab booklet. You can safely assume however that at a minimum your
goal is to get connectivity between all of the devices as outlined in
the logical topology diagram. If you have switches in the transit path
that are in transparent mode then it is implied that they must have the
VLAN configured in order to have a forwarding instance of spanning-tree
for that broadcast domain.

Hello

  what if we have a mixture of VTP server, client and also

Transperent

Or what is its all transparent, then I guest we would config the VLAN

on all switch?

I have a similar problem

Thanks for inputs

        If the VLANs span multiple switches then there's no way to test

that they are actually working without trunking configured. At some

point in the lab you're going to have to test your configurations

regardless. By building the network in a structured fashion and testing

your configurations as you go along you'll cut down on the amount of

time you need to spend troubleshooting in the long run.

Thanks Brian, what about vlans, would you do the trunking section, vtp

and then add vlans. I was thinking of adding in all vlans via notepad to

each switch then trunk, then vtp?

 

Onlu I am uncertain as to wether all switches should have all vlans

configed, sure would save time, but may be overconfiguration...

       In general you should not build a broken network in the exam, or

configure features out of order that disallow you from verifying them.

If I were in the lab exam, and the first switching section was VTP, I

would skip it and move on to trunking and then come back, since VTP

can't be verified without trunking working.

Hi Sadiq

yeah, but that would mean I have to configure VTP / trunking, and it may

be

that VTP is more than one domain, meaning that I would not be able to

config

on one switch and propogate all VLANs to other 3 switches ( as there is

more than 1 VTP domain).

I am rying to establish a methodology to save time, I think:

1. Note all VLANs in ALL switches

2. Copy to notepad and apply to ALL switches

3. Config VTP, trunking etc as required.

My concern here would be that all switches have all vlans configed

wether

they are being used or not, is this likely to cost me points? What

methodology do you guys employ?
