2、pf2使用默認(rèn)參數(shù)，則1.1.1.0/24跟11.11.11.0/24到R5就會(huì)以默認(rèn)的OE2的形式顯示，根據(jù)ospf選路原則即可選出1.1.1.0/24走R3,11.11.11.0/24走R4。同時(shí)還能互備4、R5上只啟用一個(gè)ospf進(jìn)程（不要啟動(dòng)2個(gè)進(jìn)程，ospf選路原則進(jìn)程獨(dú)立）5、回程的時(shí)候，利用ad修改本地選路即可四、配置直接貼關(guān)鍵配置了。R1:interfaceLoopback0ipaddress1.1.1.1255.255.255.0ipospfnetworkpoint-to-point!interfaceLoopback1ipaddress11.11.11.11255.255.
