SEMESTER 2 Chapter 3 Introduction to Dynamic Routing Protocols V 4.0 3.1.1 What are the four routing protocols that are the focus of this course? RIP, RIPv2, EIGRP, OSPFv2 What are routing protocols? Routing protocols are used to facilitate the exchange of routing information between routers. What is one of the primary benefits of using a dynamic routing protocol? One of the primary benefits to using a dynamic routing protocol is that routers exchange routing information whenever there is a topology change. Do dynamic routing protocols require more or less administrative overhead as compared to static routing? Compared to static routing, dynamic routing protocols require less administrative overhead. What is the expense of using dynamic routing protocols? The expense of using dynamic routing protocols is dedicating part of a router's resources for protocol operation including CPU time and network link bandwidth. 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 is the definition of what networking process? A routing protocol What are the purposes of a routing protocol? 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 List and define the three components of routing protocols? Data structures - Some routing protocols use tables and/or databases for its operations. This information is kept in RAM. Algorithm - An algorithm is a finite list of steps used in accomplishing a task. Routing protocols use algorithms for facilitating routing information and for best path determination. Routing protocol messages - Routing protocols use various types of messages to discover neighboring routers, exchange routing information, and other tasks to learn and maintain accurate information about the network. What are the four general operations of a dynamic routing protocol? The router sends and receives routing messages on its interfaces. The router shares routing messages and routing information with other routers that are using the

same routing protocol. Routers exchange routing information to learn about remote networks. When a router detects a topology change the routing protocol can advertise this change to other routers. What are the primary uses for static routing? Providing ease of routing table maintenance in smaller networks that are not expected to grow significantly. Routing to and from stub networks (see Chapter 2).
