| 摘 要： | 针对HWS9306交换机在掉头路由器组网环境下PIM-ASM（协议无关组播-任意源组播）丢包问题,详细分析问题发生的过程,对其产生的机理进行准确定位;提出通过延长表项生存时间保证流量检测覆盖全部表项的解决方法,同时进行了影响域分析;最后,在原有场景下测试并验证解决方案的有效性。此案例对网络通信问题的分析、定位及解决具有一定的指导意义。

| Abstract: | The process and location of losses of PIM-ASM packets of HWS9306 switches in a U-turn router network environment are analyzed.A solution that ensures detection coverage of all entry traffic by extending the survival time of entries is proposed and,accordingly,the influence domain is analyzed.The effectiveness of the solution is tested and validated in the original scenario.The approach is of significance to trouble-shooting in network communication. |
