Web- Root port (RP): A network port that connects to the root bridge or an upstream switch in the spanning-tree topology. There should be only one root port per VLAN on a switch. - Designated port (DP): A network port that receives and forwards BPDU frames to other switches. Designated ports provide connectivity to downstream devices and switches. on runners trainers

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.

Rapid convergence in RSTP can be achieved only on point-to-point links.

WebSep 17, 2010 · 1 Accepted Solution. 09-16-2010 11:32 PM. Actually, you are asking about port roles, not states (sorry for the nitpicking but these two are strictly differentiated in RSTP). An Alternate port provides a backup of your own Root port. If your Root port fails, the Alternate port is allowed to immediately transition into the Forwarding state and ... 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.
