What Does RSTP Mean in 200-301?
Full form: Rapid Spanning Tree Protocol
Also known as: Rapid Spanning Tree Protocol, IEEE 802.1w
Quick Definition
An enhanced version of STP that converges in seconds instead of 30–50 seconds.
Full Definition
RSTP (IEEE 802.1w) dramatically reduces STP convergence time from 30–50 seconds to typically 1–3 seconds. RSTP introduces new port roles and states: Discarding (combines blocking and listening), Learning, and Forwarding. RSTP uses synchronisation mechanisms and proposal/agreement exchanges between connected switches to rapidly transition ports to forwarding. Most modern Cisco switches run Rapid PVST+ (a Cisco enhancement of RSTP per VLAN).
Exam Trap — Don't Get Fooled
RSTP uses the Discarding state, not Blocking. Three port states in RSTP: Discarding, Learning, Forwarding. STP has five states: Disabled, Blocking, Listening, Learning, Forwarding.
