【技术分享】EIGRP的stub配置
发布作者：微思网络 发布时间：2022-10-25 浏览量：0次
配置R1： 配置R2： 配置R3： 检查R1、R2、R3路由表： 验证 EIGRP 的 stub 特性： Router(config-router)#eigrp stub [receive-only | connected | static | summary] receive-only : 不能和其他3 个参数(connected,static 和summary)一起使用.只接收从邻居路由器发送来的信息. connected : 指定该路由器可以把和它直接相连的网络信息传递给它的邻居.这个选项默认是开启的. static : 把静态路由信息传递给它的邻居. summary : 把汇总路由信息传递给它的邻居.这个选项默认也是开启的 配置R3的 EIGRP stub receive-only 特性： 在R2,R3上用show ip route 验证: 验证 EIGRP 的 stub static特性： （1）先在R3上如下设置： （2）在R2上查看路由表： 验证 EIGRP 的 stub connect 特性： （1）在R3上 no eigrp stub static （2）在R3上增加配置： （3）在R3手工汇总 （4）在R2上查看路由表 （5）在R3上手工汇总 验证EIGRP的stub summary特性: （1）在R3上: （2）在R2上查看路由表Int s1/0
