Using the vlan allowed commands with vtp

I have a large vtp domain with different branches all off of one core. Say I want to keep a vlan 5 completely off of one of these branches, I.E. no spanning tree instance for that vlan, no vlan, etc on the branch switches.

Will the vlan allowed commands let me do this, or will it just prevent traffic from that vlan 5 from communicating with traffic from the vlan 5 over on the branch switches, which was still created by vtp.

The vlan allowed command simply blocks vlans other than what is allowed and the native vlan to flow over the trunk.  It does not affect the VTP protocol.  So it would block vlan 5 traffic from flowing over the trunk, which means that switch will still have vlan 5 but it will be isolated.
