Protocol
• The original 802.1D standard only supported one STP instance for an entire switch
network. Which means that it was not possible to load share traffic across links by
blocking for specific VLANs on one line and blocking for other VLANS on alternate
links.
• Multiple Spanning Tree Protocol (MST) maps one or multiple VLANs to one STP
instance.
