Explanation:
STP mainly uses five states i.e. Learning, Listening, Blocking, Disabling and Forwarding to overcome the problem of collision in a network.
RSTP replaced the three states of STP i.e listening, learning, and blocking by Discarding, which results in the time efficiency as compared to STP.
As STP takes minutes to complete the network inter connectivity, RSTP completes it in seconds.
This is one of the main reason why an administrator want to change to RSTP.
