[c-nsp] Two different VTP-domains that interconnect with dot1q = no go?

[Roger Wiklund]

Hi.

Our company has serverar switches, so we use VTP.

So a company is renting point-to-point capacity through our network. 
At first only untagged traffic. So no problem there.

But now they want to seperate VoIP from Internet-traffic so they have 
ordered another VLAN. Well here´s the problem. The company that are 
renting also has a VTP-domain. So I noticed a VTP-domain mismatch when I 
configured a dot1q-trunk. So the result is that the tagged VLAN plus the 
native VLAN in the trunk is not working.

Is there a way to overcome this problem with two different VTP domains 
that connects with a dot1q-trunk?

Can´t I use VTP-transparent mode on port level?

Thanks

Regards
