The promise of filtering from the IRR is that you can avoid the problems
created by bogus announcements.

The problem is that the information in the IRR doesn't bear enough
resemblance to reality for people who wish to take a full feed of
Internet routes and filter them.  While some providers are good about
putting data into the IRR (or their portion of it), they often aren't
good about removing the data.

That said, on a peer to peer basis for a given peer's routes, there
isn't any reason why both peers can't agree to filter each other based
on data in the global IRR or their own local copies.  Sanity enforced
at the local level can help protect against insanity at the global level.

I find it disturbing that route filtering, especially for the larger
providers, is still being configured manually.
