NA-NP-IE系列实验实验15：RIPv2 手工汇总
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
實驗15：RIPv2 手工匯總<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 1.實驗目的 通過本實驗可以掌握： （1）RIPv2 路由的手工匯總 （2）RIPv2 不支持CIDR 匯總 （3）RIPv2 可以傳遞CIDR 匯總 2.拓撲結構 實驗拓撲如圖 所示。 ? 3.實驗步驟 路由器R1、R2 和R0的配置如下 Router>en Router#conf t Enter configuration commands, one per line.?
