From official website, suggest not use 2.6 under pip, so I need to upgrade python to 2.7 too.
But I found WAE use 2.6 after I succeed upgrade python to 2.7…Summarized the totally steps that will help me review in future.

Refer to some CASE, customer concern why BGP take so many memory resource, and how to optimize BGP, and why memory not release after optimize, and so on. That hard to answer, in order to get answer, we need check more information. From the article, you can simple to know how to check BGP memory, and how to analyzing the BGP memory, those informaiton will help you and customer to do special optimize.
In TZ database, have more good documents that is troubleshooting fabric guide on ASR9k, but no analysis process that show how to troubleshooting fabric issue on real scenario/CASE. “Very lucky” ? I matched a hot CASE that due to fabric issue cause online fail. So i summaried totally analysis process that will help CSE to narrow down similar issue.

For the issue, HuaWei is Head, asr9k should mid and end node. And Huawei found they put the traffics to Canada by LDP label, not TE label. So traffics should arrive to HK ASR9k by LDP label, then forwarding by LDP too from HK ASR9k to Canada. That not match normal scenario.
For normal scenario, should use TE label from head to end. And after Huawei put traffics to TE LSP, the issue will recovery to normal. Refer to why Huawei send traffics by LDP, that should their issue, will fix in future by them, but even if to do that, 9k shouldn’t drop packets. We need find whether packets drop at 9k and due to label issue first. Now set up test environment in customer site. waiting update.
