Hi We have witnessed a lot of prepending in the last days, we got a few internet routes that have 30...200 prepends, did you face the same issue? Regards Mihai

Not sure that this is causing an operational problem? If you don't like it, then nothing is stopping you from implementing an excess prepending policy. Nick

Hi Sandoiu, Not a direct answer to your question, but broadly speaking any route with an AS path longer than the Internet is hops wide is a mistake that can be safely filtered from your routing table. That's somewhere around 64. Regards, Bill Herrin -- For hire. https://bill.herrin.us/resume/
Always a bunch of them out there. Sometimes accidental, sometimes from folks who are trying to do something , just using ineffective methods to do it. On Tue, Oct 18, 2022 at 10:21 Sandoiu Mihai <Mihai.Sandoiu@wwz.ch> wrote:
