CCNA 200-125 Exam: RSTP Questions With Answers

WebThe same spanning tree algorithm is used for both STP and RSTP to determine port roles and topology. RSTP increases the speed of the recalculation of the spanning tree when the Layer 2 network topology changes. RSTP can achieve much faster convergence in a properly configured network, sometimes in as little as a few hundred milliseconds. 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.
