CCNA Experiment 16 fast Spanning Tree Protocol (RSTP)
Environment: Windows XP, Packet Tracer5.3
Purpose: To understand and configure RSTP
Description: RSTP: Fast Spanning Tree Protocol (Rapid spaning Trees Protocol): This kind of protocol can converge the network faster when the network structure is changed . There are only three port status forbidden ports in RSTP, blocking ports, and listening ports are much shorter than STP convergence time.
Steps:
Open Packet Tracer5.3 to create the topology:

2 , Configuration SW1 :

Switch#conf T
Switch (config) #host SW1
SW1 (config) #spanning-tr mode Rapid-pvst
SW1 (config) #
3 , Configuration SW2 :

Switch#conf T
Switch (config) #host SW2
SW2 (config) #spanning-tr mode Rapid-pvst
4 , view now STP State of:

5 , removing FA0/1 -- FA0/1 link, view SW2 the FA/10 Port Status change:
650) this.width=650; "src=" Http://hi.csdn.net/attachment/201011/21/0_1290335684Xih6.gif "/>
from the observation found FA0/10 quickly changes from blocked state to forwarding state. the RSTP convergence time is indeed much faster than STP.
