Issue with Noction IRP default setting (Was: BGP route hijack by AS10990)

Sat Aug 1 23:44:58 UTC 2020

Matt,

Why are you blaming the ease of use on the vendor, for the operators lack of knowledge regarding BGP? That is like blaming a vehicle manufacturer for a person pressing the gas pedal in a car and not giving a toss about the rules of the road. The base foundation regarding the rules of the road mostly apply the same for driving a car, truck, bus, and semi/lorry truck. There is no excuse for ignorance just because the user interface is different (web browser vs. SSH client).
Adding a take on this, there are kids born after 9/11, with IP allocations and ASNs experimenting in the DFZ right now. If they can make it work, and not cause harm to other members in this community, it clearly demonstrates a lack of knowledge, or honest human error (which will never go away).
Anything that can be used, can be misused. With that said, why shouldn't ALL BGP software implementations encourage best practice? They decided RPKI validation was a good thing.

BGP was never intended to be "optimized", it was intended to be stable and scalable. While i'm sure there are hundreds of operators that use these optimizers without incident, they are a significant paint point for the rest of the internet.

This allows users who have little experience speaking BGP with the world to make these mistakes because they don't know any better, whereas the other platforms you mention require some knowledge to configure. It's not a perfect filter, but it does create a barrier for the inept.

It should be common sense that certain routes that should be advertised beyond the local AS, just like RFC1918 routes, and more. Also, wasn't it you that said Cisco routers had a bug in ignoring NO_EXPORT? Would you go on a rant with Cisco, even if Noction add that enabled checkbox by default?

One solution would be to implement "BGP Group/Session Profiles" (ISP/RTBH/DDOS Filtering/Route Optimizers/etc) or a "BGP Session Wizard" (ask the operator questions about their intentions), then automatically generate import and export policies based on known accepted practices.

That would be useful in getting around vendor specific issues, as well as belt & suspenders protection.
