The problem with STP, however, is that STP convergence time islong, which makes it not suitable for users who have high demand on convergence speed.For more information about STP, refer to MSTP Configuration in the Access Volume.Smart Link is a feature developed to address the slow convergence issue with STP. It provides linkredundancy as well as fast convergence in a dual uplink network, allowing the backup link to take overquickly when the primary link fails. To sum up, Smart Link features the following:z Dedicated to dual uplink networksz Subsecond convergencez Easy to configureFigure 1-1 shows a Smart Link application scenario.Figure 1-1 Smart Link application scenarioDevice ADevice BDevice C Device EDevice DGE1/0/1 GE1/0/2GE1/0/1GE1/0/2GE1/0/2GE1/0/3GE1/0/1GE1/0/1GE1/0/1GE1/0/2GE1/0/2GE1/0/3
