【技术分享】EIGRP的stub配置
发布作者：微思网络 发布时间：2022-10-21 浏览量：0次
配置R1： 配置R2： 配置R3： 检查R1、R2、R3路由表： 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: 2、在R2上查看路由表: 验证EIGRP的stub connect特性: 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手工汇总 2、在R2上查看路由表Int s1/0

验证EIGRP的stub static特性:
1、现在R3上如下配置：R3(config)#ip route 44.1.1.0 255.255.255.0 ethernet 0/0 //增加一条静态路由
R3(config)#router eigrp 100
R3(config-router)#redistribute static //把静态路由发布到EIGRP中
R3(config-router)#R2#show ip route eigrp //有44.1.1.0的路由但没有connect 33.1.1.0的路由
