Hi. Does anyone here on this list filter BGP routes learnt with prefixes longer than /24 ? Thanks, Adrian -- Adrian Chadd | "Once in a lifetime, you find someone, <adrian@creative.net.au> | Who touches not only your heart, | But also your soul."

Before people look at me crazily ("Longer than /24? Why bother?") let me rephrase that to filter OUT /24s (eg filtering at /23, or /19 ..) Sorry, I need more caffiene.. :) Adrian
Most folks filter very similar to the agis policy posted at http://www.nanog.org/filter.html In addition, some folks filter some of the good old class A space at /8, except for the 24/8. - Jared On a dark and stormy night, Adrian Chadd said:

Okay, hold it.. I'm confused. Are you saying 1) filter /24 -> /32 or 2) are you saying filter /24 -> /8? if 1) = true; then echo "read previous email with clear conscience" if 2) = true; then echo "are you mad?!" done =) On Tue, 21 Apr 1998, Adrian Chadd wrote: :Adrian Chadd writes: :> :>Hi. :> :>Does anyone here on this list filter BGP routes learnt with prefixes longer :>than /24 ? : :Before people look at me crazily ("Longer than /24?

Yep. I thought that was pretty common? ------------------------------------------------------------------ Jon Lewis <jlewis@fdt.net> | Network Administrator | Florida Digital Turnpike | ______http://inorganic5.fdt.net/~jlewis/pgp for PGP public key____
Okay, I'm missing something.. I assume you are talking about filtering from /24 -> /8, right? WHY?! Unless something is flying over my head, this would totally break the concept that CIDR is trying to fix.. I'm lost! %P On Tue, 21 Apr 1998, Jon Lewis wrote: :On Tue, 21 Apr 1998, Adrian Chadd wrote: : :> Does anyone here on this list filter BGP routes learnt with prefixes longer :> than /24 ? : :Yep.

I'm taking full tables from 3 backbones and I have yet to see anything advertised longer then a /24. Are you seeing some?
