tailieunhanh - Lecture Building a Simple Network: Enabling RIP

In this chapter, you learned to: Encounter and describe the limitations of RIPv1’s limitations, apply the basic Routing Information Protocol Version 2 (RIPv2) configuration commands and evaluate RIPv2 classless routing updates, analyze router output to see RIPv2 support for VLSM and CIDR,. | Enabling RIP Routing protocols are used between routers to determine paths and maintain routing tables. After the path is determined, a router can route a routed protocol. What Is a Routing Protocol? Purpose: This figure introduces students to routing protocols and compares routing protocols to routed protocols. Emphasize: If network wants to know about network , it must learn it from its S0 (or possibly S1) interface. Note: The two routing protocols that will be taught in this course are RIP and IGRP. They are both distance vector routing protocols. An autonomous system is a collection of networks under a common administrative domain. IGPs operate within an autonomous system. EGPs connect different autonomous systems. Autonomous Systems: Interior or Exterior Routing Protocols Purpose: This figure discusses autonomous systems, IGPs and EGPs. Emphasize: Introduce the interior/exterior distinctions for routing protocols, as follows: Interior routing protocols are . | Enabling RIP Routing protocols are used between routers to determine paths and maintain routing tables.

Emphasize: Introduce the interior/exterior distinctions for routing protocols, as follows: Interior routing protocols are used within a single autonomous system Exterior routing protocols are used to communicate between autonomous systems The design criteria for an interior routing protocol require it to find the best path through the network. In other words, the metric and how that metric is used is the most important element in an interior routing protocol. Exterior protocols are used to exchange routing information between networks that do not share a common administration. IP exterior gateway protocols require the following three sets of information before routing can begin: A list of neighbor (or peer) routers or access servers with which to exchange routing information A list of networks to advertise as directly reachable The autonomous system number of the local router Classes of Routing Protocols Purpose: This figure introduces the three classes of routing protocols. Emphasize: There is no single best routing protocol. Note: Distance vector routing protocol operation is covered in detail later in .
