适用场景

ONTAP 9.2及更高版本

问题描述

  • ONTAP 在需要启动新请求或回复请求时如何选择路由。
  • 要确定目标的最特定路由、请从ONTAP 命令行界面运行以下命令:​​​​​​
    • set advanced; network route active-entry show -vserver vserver -node node-01 
    • 其中包括从指定节点上的LIF发出的路由
      • 命令"route show"将仅显示路由配置(而不是路由表中的实际路由)
    • 或者、也可以在ActiveIQ的AutoSupport 部分查看route-active.XML 
  • 在路由匹配项中、确定前缀最长的路由
    • 例如、如果目标IP地址为10.1.1.1、则查看具有以下目标的路由表
      • "default"或0.0.0.0/0匹配且前缀为0位
      • 10.1/16匹配且前缀为16位
      • 10.1.1/24匹配且前缀为24位
      • 10.1.1.1/32匹配并具有32位前缀、该前缀是最长的前缀(32大于24、16和0)、因此它是最具体的路由
