Rapid per-VLAN spanning-tree plus
RPVST+ is an RSTP to create a single topology per VLAN. RPVST+ is enabled by default, provides faster convergence, and runs on the
default VLAN (VLAN 1).
Conguring Rapid-PVST+ is a four-step process:
1 Ensure the interfaces are in L2 mode.
2 Place the interfaces in VLANs. By default, switchport interfaces are members of the default (VLAN1).
3 Enable Rapid-PVST+. This step is only required if another variation of STP is present.
4 (Optional) Select a non-default bridge-priority for the VLAN for load balancing.
