7.4 Configuring STP/RSTP Parameters on an Interface
STP does not have a mechanism to confirm topology convergence, whereas RSTP provides a
feedback mechanism to implement rapid convergence.
STP does not implement rapid convergence; however, STP parameters such as the network
diameter, Hello timer, Max Age timer, and Forward Delay timer, may affect network
