filter-list可以根据路由的属性(如路由器ID、序列号等)或者路由的路径(如进入接口、来源AS等)进行过滤,灵活应用于不同的网络场景中。 在实际应用中,ospf filter-list能够帮助网络管理员解决一系列的问题。首先,filter-list可以帮助网络管理员优化网络拓扑,避免出现路由环路、冗余路由等问题,提高网络传输效率和稳定性。...

filter命令用来配置对进出本区域的Type-3 LSA进行过滤。undo filter命令用来取消对Type-3 LSA的过滤。缺省情况下,没有对Type-3 LSA进行过滤。此命令只在ABR路由器上有效,对区域内部路由器无效。【举例】# 根据地址前缀列表my-prefix-list和编号为2000的ACL分别对进出OSPF区域1的Type-3 LSA进行过滤。
