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*RSTP roles: - Root Port: Port closest to the Root Bridge in forwarding state - Designated Port: Of all Switch ports on all switches attached to the same. segment/collision domain, the port that advertises the "best" BPDU. - Alternate Port: This is a port that provides an alternative path to the root bridge.
