Addressing Scheme and Basic Configuration for Campus Network

This article discusses the addressing scheme and basic configuration for a campus network, including the network addresses, subnet masks, and default gateways for various devices. It also covers the configuration of RIP, static routes, ACLs, and connectivity verification.
