Hi,
I'm looking at a number of transit providers in Europe who offer
communities that will limit the scope of an announcement by
geographic region. For example if you are AS1 you can tell upstream
AS2 to propagate your announcements only to peers and neighbors
within EU, but not those in the NA or AP regions. This helps
networks with unique routing policies. (If you're curious what these
might be, just ping me offlist) I'm looking for feedback from people
who have done this before. All advice, experiences (preferably with
what upstream ASNs) is helpful. Our concerns are basically that this
puts a management and engineering aspect of our network into someone
else's hands to not mess up. I already know we deal with peers who
leak routes, but my guess is that since this is a business
relationship with the upstream network they are less likely to bork
it up and hopefully manage it programatically. Wishful thinking or
sound practice/service offered by high-quality carriers?
My questions are thus:
1) I'd this to find out how reliable it is/was (were your routes ever
leaked)?
2) How effective it is/was (did it accomplish your goals)?
3) Advice you might have for someone who is considering doing this?
Providers to shy away from? Providers who are pretty good?
Thanks,
David Ulevitch
