Who uses RADB/IRR?

Actually, we just became multihomed last month. I'm not aware of any
problems getting to other parts of the net, and definitely no problems with
C&W.

[Also, my apologies if this a newbie BGP question]

I started looking at the RADB, but haven't got ourselves setup yet. Does
anyone actually deny routes which aren't listed in the RADB? I guess what
I'm really asking is how important is it to be in the RADB? Does it get
more important sometime soon?

I would also tend to think [based on limited BGP knowledge] that it would
only be a problem if your direct upstream used the RADB or if your upstream
is RADB filtered by their peers. Is this true?

Depends on what you mean by deny. If you are generating access-lists
from RAdb entries, obviously you will only be accepting those routes.
Unless you were doing as_path based filtering, you are implicitly
filtering those other routes. Manually adding unregistered routes would
alleviate this problem until you had convinced them it was in their
interest to register.

It's not like you won't be able to peer with anyone after a certain
date, but there are important reasons to register.

-If you are multihomed, your upstreams will have synchronized access-lists
  allowing you more control over the shape of your traffic.
-Convenient automated, synchronized and *authenticated* updates to your peers.
-Portable central source for customer and local routing information.
-Making IPMA/Merit/CAIDA projects more accurate.

Am I correct in thinking that ANS and CAnet both require registration
of their customers routes?

I'm sure that a site that used RtConfig for generating access-lists
would only do so for customers that had assured the site that their
registrations were current and worthy of production. Otherwise,
routes are added manually.
