Hello
This 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:
