本帖最后由 weidhuan 于 2015-6-29 13:57 编辑 理解 Show IP OSPF Traffic 命令
简介： 本文主要阐述在 OSPFv2 和 OSPFv3 里的
show ip ospf traffic 命令。通过显示详细的 OSPF 网络流量统计信息，show ip ospf traffic 能够帮助我们更加有效地对 OSPF 进程进行排障。
OSPF 流量统计会采集并显示以下信息：
- OSPF hello 入向队列和 OSPF 进程队列的状态及统计信息
- 全局 OSPF 流量统计信息
- 每个 OSPF 接口的流量统计信息
- 每个 OSPF 进程的流量统计信息
当 OSPF 网络出现不稳定的状况时，OSPF 进程队列的状态以及它的统计信息，能够帮助我们确定有多少流量可以被送到 OSPF 中。例如，我们可以利用这些输出，来确定 OSPF 进程处理的流量的总值。
同时，OSPF 数据包报头错误和 LSA 错误统计将有助于对各种不同的错误进行分类记录。
针对存在低速链路和频繁拓扑变更的典型的本地网络环境，你还能够监控 OSPF 进程间交互的流量控制报文的数量。
