George,
VTP doesn't relate to actual traffic within the VLAN. VTP is
used just to advertise the existence of a VLAN and its parameters for
the purpose of easier administration. The "allowed list" on the other
hand is used to control what VLAN traffic can or cannot be sent over the
link. In your case you set the allowed list to only VLAN 10. This
means that traffic from VLANs 1-9 and 11-4094 will not be able to be
sent over that link. If the switches are in the same VTP domain and
running as server or client mode they would still learn about the
existence of the VLANs even though they couldn't send traffic for them
over the link. With transparent mode they don't exchange information
about their locally configured VLANs so you need to create the VLANs on
both devices.
