EIGRP

Dynamic Route Guidance System Based on EIGRP

基于EIGRP协议的动态路径诱导系统

Several new features and capabilities have been integrated into EIGRP in the last several years , and many more are planned .

在过去几年里，几种新型性能和功能已经集成到EIGRP，并且还规划了众多功能。

In network design , it analyzes layer 3 topology , VLAN segmentation , layer 3 switching , EIGRP routing protocol , and PIX firewall configuration .

在网络设计中详细介绍了三层网络拓扑结构、Vlan划分、三层交换技术、EIGRP路由协议、PIX防火墙配置等。

So cisco company puts forward to EIGRP ( enhanced interior gateway routing protocol ), it takes in the advantages of RIP and OSPF . Now EIGRP is widely used in cisco router .

于是cisco公司推出了结合两种优点的平衡混合型路由协议――EIGRP（增强型内部网关路由协议），该协议为cisco公司的专有协议，在cisco路由器上用的十分普遍。

The article discuss about the system interface part of the software : the process of sending and receiving the EIGRP packet , the command process from the configure shell process , the show process of the EIGRP , the adding and deleting route process and so on .

本文主要讲述的是软件中的系统接口部分：EIGRP数据包的接收与发送，EIGRP协议的配置命令处理，EIGRP协议的显示信息，EIGRP协议的路由添加和删除等问题和系统框架。

At first , the article introduces some concepts of EIGRP and something detail about DUAL , such as : EIGRP metrics , successor , feasible successor , feasible distance , feasible condition . We also compare EIGRP with RIP and OSPF to demonstrate which is the advantage of EIGRP .

本文首先介绍了EIGRP的一些基本概念：EIGRP距离、后继、可行后继、可行距离、可行条件和核心算法DUAL，并与RIP和OSPF做了简单比较，说明了EIGRP的优点究竟在哪里。
