Classic STP runs one spanning tree for the entire switched network, no matter how many VLANs exist. That means every VLAN shares the same root bridge and the same blocked links — one uplink ends up carrying nothing while every other uplink carries everything, regardless of which VLANs actually need which paths.

What is PVST+ – Revolutionize VLAN Load Balancing and Banish Network Loops Forever (Updated 2025)
The original IEEE 802.1D standard spanning tree protocol assumes only one spanning-tree instance for the entire switched network, regardless of the number of VLANs. A network running cannot ensure load balancing because one uplink must block all VLANs, but the CPU is free because there is only one instance of a spanning tree working. The...
