■ Scalability— A scalable solution must allow a network to grow into the future. The
network must be designed to allow growth in the following areas:
— Topology—A topology must be selected so that changes do not require
major reconfiguration of the entire network.
— Addressing—The addressing scheme that you choose should be affected
only minimally by changes to the network and should allow for route
summarization.
— Routing protocols—The design should be such that changes in the
network are easily handled by the routing protocols.
