  • What is a convergence switch

    What is a convergence switch

    Convergence is the state of a set of that have the same information about the in which they. Convergence is an important notion for a set of routers that engage in dynamic routing. All interior gateway protocols rely on convergence to function properly. "To have, or be, converged" is the normal state of an operational autonomous system.Convergence processWhen a routing protocol process is enabled, every participating router will attempt to exchange information about the topology of the network. The extent of this information exchange, the way it is sent and receive. Convergence time is a measure of how fast a group of routers reach the state of convergence. It is one of the main design goals and an important performance indicator for, which should implement.
