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).
Conguring 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.
By default, each VLAN instance is assigned default bridge priority 32768. For example, all three instances have the same forwarding
topology. Trac load balancing is not achievable with this kind of priority assignment. To achieve load balancing, you must assign each
instance a dierent priority, as shown in Load Balancing with RPVST+.
