请问下这个拓扑下做双点双向重分发为什么还会有R的路由？
本帖最后由 Mr.黄瓜 于 2013-12-15 19:12 编辑我在R2,R3上做rip和ospf的双向重分发，但是为什么R3上看到去往4.4.4.4的却是rip学到的呢？不是应该ospf的优先于rip的吗？？
还个问题就是如何实验双点双向重分发引起的环路问题？

原因很简单··因为你在R3上面将带R的4.4.4.4重分布了 OSPF。所以R2学习到的4.4.4.4 是OE2的。虽然你在R2上面 将RIP的路由重分布了进OSPF ，但是R2上面4.4.4.4的路由是带OE2的，也就是非R得路由。所以无法执行该路由的重分布，R3也就无法通过OSPF学习到4.4.4.4的路由。所以R3的4.4.4.4的路由依旧是带R的··· 要解决这个问题只需要R2的4.4.4.4的路由的管理距离比RIP大即。同时R3的4.4.4.4的路由管理距离也要比RIP大。防止次优路径 本帖最后由 Mr.黄瓜 于 2013-12-15 20:30 编辑
