While STP can take 30 to 50 seconds to respond to a topology change, RSTP is typically able to respond to changes within 3*Hello times (default: 6 seconds).

Unlike STP I understand that RSTP has three timing intervals before it begins to converge. RSTP Hello timer >>> 2 seconds MAX-AGE >>> 6 seconds Forward-Delay (Learning) >>> ? seconds Default convergence time ? STP Hello timer >>> 2 seconds MAX-AGE >>> 20 seconds Forward-Delay (Listening) >>> 15 seconds Forward-Delay (Learning) >>> 15 seconds Default convergence time 50 seconds If I am understanding things correctly 1.The Hello interval are the same as STP which is every 2 seconds. 2. The default Max-Age time for RSTP is 3 times the hello interval or 6 seconds. 3.RSTP elminates the listening state however, there is a learning state. What is the default time that RSTP stays in the learning state before is transitions to either forwarding or discarding? -------------------------------------------------------------------------------- _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
