VTP transparent question

[katerina.dardoufa]

Hello community!

A switch set to VTP mode transparent does not require a VTP domain name.

Is it wrong to configure one none the less, just to know to what the switch is used for, say for example when you see it in topology services of CW?

I suppose that configuring it won't have an impact on the rest of the network, but I still would like to listen to suggestions.

What I really want to do is attach a switch to the production network, but that switch is going to belong to the DMZ. I only want to pass the two vlans from the core to this switch and also add another one, that I don't want to propagate to the internal network.

So I was thinking of the following config for the DMZ switch:

VTP version2

VTP mode transparent

VTP domain DMZ

vlan 2 (already runs in internal network)

vlan 3 (already runs in internal network)

vlan 4 (new and only on DMZ)

connection to 65xx

switchport mode trunk

switchport trunk allowed vlans 2,3

Will this work?

Thanks in advance,

Katerina

Presuably that VTP domain ie. DMZ is not the same as the VTP domain on your other switches ?

It will work fine. Make sure you turn off dynamic neogotiation of trunks and set the trunk mode to on at both ends if the VTP domains are different.

Hi Jon and thanks for your reply!

VTP Domain DMZ is different than the VTP domain used in the rest of the internal network.

Thanks also for the extra tips.

I'll try it and see how it goes.

It seems that everything is working!

Thank you very much!
