Web• When RSTP uses 802.1D BPDUs on a port and receives an RSTP BPDU after the migration delay expires, RSTP restarts the migration delay timer and begins using RSTP BPDUs on that port. RSTP Port Roles In RSTP, the port roles are defined as follows: • Root—A forwarding port elected for the spanning tree topology. WebApr 2, 2024 · In a stable topology with consistent port roles throughout the network, the RSTP ensures that every root port and designated port immediately transition to the forwarding state while all alternate and backup ports are always in the discarding state (equivalent to blocking in IEEE 802.1D).
