At a minimum, the documentation should include a topology diagram that indicates the physical connectivity and an addressing table that lists all of the following information: Device names Interfaces used in the design IP addresses and subnet masks Default gateway addresses for end devices, such as PCs Implementing Basic Addressing Implementing Basic Addressing Basic Router Configuration Router name Passwords Banner Basic Router Configuration Basic Router Configuration Verifying Basic Router . | Chapter4: ROUTING MẠNG MÁY TÍNH NÂNG CAO ROUTING Introduction to Routing and Packet Forwarding Routers determine the best path The primary responsibility of a router is to direct packets destined for local and remote networks by: Determining the best path to send packets Forwarding packets toward their destination Routers determine the best path Routers determine the best path Implementing Basic Addressing When designing a new network or mapping an existing network, document the network.

Routing Table is stored in RAM and contains information about: Directly connected networks -this occurs when a device is connected to another router interface Remotely connected networks -this is a network that is not directly connected to a particular router Detailed information about the networks include source of
