What is benefit of PVST+?
supports Layer 3 load balancing without loops.|
reduces the CPU cycles for all the switches in the network.|
allows the root switch location to be optimized per VLAN.|
automatically selects the root bridge location, to provide optimized bandwidth usage.|
Per VLAN Spanning Tree (PVST) maintains a spanning tree instance for each VLAN configured in the network. This means a switch can be the root bridge of a VLAN while another switch can be the root bridge of other VLANs in a common topology.
