Are VTP Advertisements Sent over Spanning Tree Blocked Links?

In a Virtual Terminal Protocol (VTP) domain there are 6506 switches, 4912G units and many 35xx units. There are more than 64 VLANs in use, so there are no redundant links due to the 35xx restriction of 64 spanning trees.

Should this be split into three VTP domains to make sure there are no more than 64 VLANs on any 35xx? In this scenario, some of the switches would be connected to one neighbour in the same domain but to other neighbours in other domains. How can we ensure that the first link is not spanning tree blocked for VTP to work?

Re: Are VTP Advertisements Sent over Spanning Tree Blocked Links

First, VTP is passed on VLAN 1 and

can be sent and received through blocked

ports.

Second, spantree topology and VTP are totally independent. So, spantree would still block

or forward normally on a link regardless of whether

the switches on each side are in different VTP

domains.
