我正在尝试了解 BGP 和展望服务器的概念。stackexchange的 IP 地址是198.252.206.140
. 现在,我使用这里的窥镜服务器。
- 我选择了BGP 网络并单击了提交按钮。
- 我将窥镜服务器的起始位置指定为 Australia 并尝试跟踪流量直到stackexchange。因此,我将 IP 地址指定为
198.252.206.140
.
现在,这是我得到的输出。

据我目前了解,数字 4637、174 和 25791 是路线的编号。另外,根据输出,我得到 4 条路径,最佳路径是#3。那么,我必须在此输出中查看什么才能了解为什么 #3 是最佳路径或路线?或者换句话说,如何从窥镜服务器破译这个输出?
我经历了这个问题,这帮助我理解了这些概念。但我仍在寻找一种方法来破译窥镜服务器的输出。
