思科设备eigrp协议配置.docx

本次讲解路由器eigrp协议的配置：1EIGRP与IGRP在network命令的区别在于多了wildcard-mask参数，这是通配符掩码。如果网络定义使用的是默认掩码，则wildcard-mask参数可以省略：如果网络定义使用的不是默认掩码，则wildcard-mask参数必须标明。 2EIGRP在处理有类别(A、B、C类)网络地址时，会自动地汇总路由。这意味着即使规定RTC 连接的是10030/24这个网络，但EIGRP仍然会发布其连接整个A类网络10000。在EIGRP中，路由自动汇总功能默认是有效的。存在不连续子网的网络中，通常需要用no auto-summary命令来关闭该功能。本例配置模型图命令行：RA配置命令：RouterRouterenableRouter#conf tEnter configuration commands, one per line.
