1. Pvrst + is an enhanced function of RSTP, which can be used with VLAN to better control the traffic in the network. Maintain a separate spanning tree for each active VLAN in the network, provide load balance through multiple instances of spanning tree, fault tolerance (because the failure of one instance of spanning tree will not affect other spanning trees), and support RSTP through rapid reconfiguration
fast spanning tree is a link management protocol, which provides path rendancy and prevents unnecessary loops in the network, such as multiple active paths between sites. In order to establish path rendancy, STP creates a tree across all switches in the extended network to force the rendant path into standby or blocking state
to make the Ethernet network work normally, there can only be one active path between two stations. Multiple active paths between stations in the bridge network can lead to infinite cycles of Ethernet frames. STP can break the cycle logically and prevent the network from being blocked by cycle traffic. Dynamic control of topology provides continuous network operation in the presence of rendant or unexpected cyclic paths.
