RIPv2、EIGRP&OSPF between 4 Routers


今天要來實作RIPv2、EIGRP&OSPF三個路由協定共存時,透過Redistribute的機制來分享其他路由的資訊,設定時要注意的重點有二,一為因R3為所有橋接邊界的Router,在設定EIGRP分享網段時必須所有相接的都要做設定,而同時共存的RIPv2和OSPF則只設定相對應的網段即可,另一則為OSPF沒有No Auto-Sum的指令,且在做Redistribute時若沒加上subnet會強迫用Classful的觀點來檢查設定網段,還有若只有指定Metric時是屬於N2的類型,也就是在Area內只接受Redistribute所指定固定的Metric(不會再另做計算),所以改用Metric-type為N1類型時則會按照原本OSPF的機制做Metric的運算(參考此處的說明);因此廢話不多說,直接上實作,如下: Read more »
