Objective: Describe the role of dynamic routing protocols and place these protocols in the context of modern network design. Identify several ways to classify routing protocols. Describe how metrics are used by routing protocols and identify the metric types used by dynamic routing protocols. | Chapter05 DYNAMIC ROUTING MẠNG MÁY TÍNH NÂNG CAO PART 1: INTRODUCTION TO DYNAMIC ROUTING Objective Describe the role of dynamic routing protocols and place these protocols in the context of modern network design. Identify several ways to classify routing protocols. Describe how metrics are used by routing protocols and identify the metric types used by dynamic routing protocols. Determine the administrative distance (AD) of a route and describe its importance in the routing process. Identify the different elements of the routing table The Evolution of Dynamic Routing Protocols The Role of Dynamic Routing Protocol Routing protocols are used to facilitate the exchange of routing information between routers. Routing protocols allow routers to dynamically share information about remote networks and automatically add this information to their own routing tables. Routing protocols determine the best path to each network which is then added to the routing table.

Routing protocols allow routers to dynamically share information about remote networks and automatically add this information to their own routing tables. Routing protocols determine the best path to each network which is then added to the routing table. Network discovery A routing protocol is a set of processes, algorithms, and messages that are used to exchange routing information and populate the routing table with the routing protocol's choice of best paths. The purpose of a routing protocol includes: Discovery of remote networks Maintaining up-to-date routing information Choosing the best path to destination networks Ability to find a new best path if the current path is no longer available Components of a routing protocol: Data structures Algorithm Routing protocol messages Dynamic Routing Protocol Operation All routing protocols have the same purpose -to learn about remote networks and to quickly adapt whenever there is a change in the topology. Dynamic versus Static Routing Classifying Dynamic Routing Protocols IGP and EGP An autonomous system (AS)-known as a routing domain -is a collection of routers under a common administration. Two types of routing protocols are: interior and exterior gateway protocols. IGPs are used for intra-autonomous system .
