Ping远程主机返回“TTL expired in transit.”[转]

发布:admin | 发布时间: 2010年5月18日

故障现象：

双方都是ADSL线路，一个在北京，一个在上海，从上海Ping北京IP 222.128.XX.191返回如下结果：

C:\>ping 222.128.XX.191

网络参考：

网上搜索了一下，解释如下：

导致这个问题出现的原因有两个：

1）TTL值太小！TTL值小于你和对方主机之间经过的路由器数目。

2）路由器数量太多，经过路由器的数量大于TTL值！

问题分析：

使用TRACERT命令查看所经过的路由路径：

C:\>tracert 222.128.XX.191
