What are the two reasons an organization does not use a single router to connect all its networks?
What will be an ideal response?
An organization seldom uses a single router to connect all of its networks. There are two
major reasons:
? Because the router must forward each packet, the processor in a given router is insufficient to
handle the traffic passing among an arbitrary number of networks.
? Redundancy improves internet reliability. To avoid a single point of failure, protocol software
continuously monitors internet connections and instructs routers to send traffic along
alternative paths when a network or router fails.
