The previous book in this series, The Packet Guide to Core Network Protocols , covered the IPv4 protocols, masking, and devices that are part of every network. There are an astonishing number of table-based decisions that have to be made in order to get a single packet across a network, let alone across a series of networks. Not limited to routers, switches, and access points, these decisions are made at each and every device, including hosts. As networks are constructed and devices configured to forward packets and frames, network administrators must make critical decisions affecting performance, security, and optimization. When moving to advanced ideas, the net admin should know how and why networking tables are constructed, and in what cases manual changes will be beneficial.

Router and Routing Basics

Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks , such as the public switched telephone network PSTN , and computer networks , such as the Internet. In packet switching networks, routing is the higher-level decision making that directs network packets from their source toward their destination through intermediate network nodes by specific packet forwarding mechanisms. Packet forwarding is the transit of network packets from one network interface to another. Intermediate nodes are typically network hardware devices such as routers , gateways , firewalls , or switches. General-purpose computers also forward packets and perform routing, although they have no specially optimized hardware for the task. The routing process usually directs forwarding on the basis of routing tables.

This tutorial explains the basic concepts, features, functions, and types of routing protocols. Learn different types of routing protocols and how they work in detail. There are three types of routing protocols: distance-vector, link-state, and hybrid. Routers running distance-vector routing protocols periodically broadcast routing and reachability information from all active interfaces. They also receive the same information from their neighbors on their active interfaces. Distance-vector protocols use timers to broadcast routing information. Once their periodic timer expires, they broadcast their routing information from all active interfaces, no matter whether the routing information has changed since the previous broadcast or not.

Routing outbound

A routing protocol specifies how routers communicate with each other to distribute information that enables them to select routes between nodes on a computer network. Routers perform the traffic directing functions on the Internet; data packets are forwarded through the networks of the internet from router to router until they reach their destination computer. Routing algorithms determine the specific choice of route. Each router has a prior knowledge only of networks attached to it directly. A routing protocol shares this information first among immediate neighbors, and then throughout the network.
