Generally speaking, if both the destination and the origination points are on the same network, the traffic is unlikely to leave that network. So to see evidence that CN2 is in our blend, one can perform a traceroute originating on CN2 and see it take CN2 the whole way.
Here is China Telecom’s looking glass, where you can choose to send the traffic over CN2. If you run a traceroute to our network, for example to 107.167.3.4, you should generally see it ride CN2 the entire length of the traceroute. Select “Traceroute” in the first column, CN2 and Hong Kong in the second column, and our IP 107.167.3.4 in the third column. Here’s an example from January 25th, 2018 at approximately 9am PST:
Query Results:
Source: 203.100.48.27
Destination: 107.167.3.4

IP Version: IPv4
traceroute 107.167. < ~]# traceroute 107.167.3 .4

如果我在忽悠就没什么意义了,昨天我和sharktech的人已经联系过了,他们给出的结论就是这是BGP选择的结果,我就是用电信,但是测过了是4134,他们告诉我的方法是只能通过一个纯CN2来验证,他们说服务器的outbound是可以自己控制选择的,你看看他们的文章看看他们的测试方法。 |
