Hi folks... I would like to know whether folks are limiting their peering sessions (BGP peering at public exchanges) only by max-prefix typically? Are we the only folks trying to filter all peers using IRR information? We've run across several peers now with 10,000+ prefixes who do not register barely half their prefixes in an IRR ... meaning that we deny the rest by default. I like to think that filtering on IRR is much better (not perfect by any means) as a practice but it's probably more *practical* to just limit max-prefix peers? We can't force our peers to register at a IRR and the only party that pays the price is us in that sense.. Am I thinking right on this? ;) Cheers, Paul ---------------------------------------------------------------------------- "The information transmitted is intended only for the person or entity to which it is addressed and contains confidential and/or privileged material.

No, you're not the only ones.

Most peering agreements I have read require either registration of routes in an appropriate place or notification to the other party of an appropriate filter for their routes and/or AS path. In Au we have multi-lateral peering exchanges and at least the one $work is on requires registration of routes with the exchange provider who generates the appropriate filters. cheers marty -- supine: From the Latin for "lying on one's back," to be supine has come to mean "inactive." But as Damien Hirst suggests with his maxim "Minimum effort for maximum effect," there's nothing wrong with being inactive. "An Idler's Glossary" - http://www.hermenaut.com/a158.shtml
