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