[c-nsp] VTP and Vlan 1

Hi Mike
Actually VLAN 1 is not pruning-eligible so you can not prune VLAN 1 from a
trunk. However you can remove it from the trunk.
If you remove it from the trunk and change the native VLAN for the trunk,
VTP will then use the new native VLAN for updates.
best regards

Michel
