1、實驗路由策略一實驗拓撲圖1實驗一實驗要求：原本網(wǎng)絡(luò)使用EIGRP現(xiàn)在要求用OSPF來發(fā)現(xiàn)網(wǎng)絡(luò)拓撲。實驗分析：要是網(wǎng)絡(luò)平滑過渡可先將OSPF配置好，然后理由改變EIGRP的管理距離使OSPF替換EIGRP進路由表，等到全網(wǎng)為OSPF后，去掉EIGRP.實驗操作及結(jié)果：首先全網(wǎng)為EIGRP如下r1#showiproute192.168.12.0/30issubnetted,1subnetsC192.168.12.0isdirectlyconnected,Serial0/0192.168.23.0/30issubnetted,1subnetsD192.168.23.0[90/]via192
