Initial diagnosis:
A BGP routing collection and analysis project sent unexpected BGP I/O flow, which led to Juniper routing core dump.

Solved. DDoS Mitigation Cluster has routing loop issues. Huge DDoS used up the entire bandwidth capacity of the core router. The router tried to reset all interfaces on the PFE to "solve" this issue. To save FIB, the DDoS Cluster has no full FIB, it shares…
This is not the major reason that caused the CR core dump at last month. After reviewing both dump logs. This is caused by unsupported BGP operations sent from the RIS project.
There are no problems at JunOS 15.x; but it happened after we upgrade to Jtac recommended JunOS 20.x. We’ll follow with Jtac once our new MPC line card has arrived.

LAX.sPro(CFMT)'s IPv4 address space is running out, and it will take time for us to replenish the IPv4 address. Please order ahead if you may need the services recently.
TYO maintain:
- Reboot to apply DMIT kernel patch for PVE.
++ Improve network stability.
++ Drop unrelated Layer 2/3/4 packet with current client VM.
++ Remove PVE heavy network bridge architecture.
++ Remove PVE heavy firewall architecture.

Dear Affer & Client:
The network routing for DMIT standard network profile(LITE) is dynamic.
DMIT does not offer any kind of guarantee of the IP Transit, backbone, peering, upstream, downstream on the standard network profile.
It might be changed, upgraded, degraded, replaced at any time. It depends on the costs of it.
Please also do not assume we will guarantee anything if we didn't make the promise in the order, contract or TOS. For example: the "Native IP?"
DMIT is an IaaS / SaaS cloud services provider. We don't want to work on this kind of unsustainable request or service.
For example, we give China optimization on Pro, we will promise it always be included during the service.
DMIT will try our best on Lite, but we cannot give any kind of guarantee. It might suit you right now but it might not after a long time later. We didn't have promises from others(upstream, etc), so we cannot give that promise to you.
We will update TOS about Lite and there is no guarantee for anything we don't promise.

CN2(AS4809) backbone is currently unstable.
The packet loss rate might higher than normal. DMIT NOC has already reached CTGNOC about this situation.

We put an inappropriate filter policy on the AS4809 interface which lead to unable to trace the routing from DMIT to China.
