HelloThis morning we apparently had a problem with our routers not handling the full table. So I am looking into culling the least useful prefixes from our tables. I can hardly be the first one to take on that kind of project, and I am wondering if there is a ready made prefix list or similar?Or maybe we have a list of worst offenders? I am looking for ASN that announces a lot of unnecessary /24 prefixes and which happens to be far away from us? I would filter those to something like /20 and then just have a default route to catch all.
This may be too old to be terribly useful other than as a starting point, but we went through essentially the same thing a little more than 10 years ago:
