I wonder why people don't drop any update that contains stuff like RFC 1918 space. -- Requiescas in pace o email Two identifying characteristics of System Administrators: Ex turpi causa non oritur actio Infallibility, and the ability to learn from their mistakes. (Adapted from Stephen Pinker)
This should now be fixed. As a general matter of policy, we do filter out 10/8, but somehow the filter list for a customer was empty which then defaults to an implicit accept. We're in the process of improving our config audits to catch this in the future.

what happens if they register a route object for 10/8? :)

Perhaps we should all take a moment and review RFC 5735, 6598, 6890, and 5156 and implement filtering in the appropriate places and help make the Internet a safer place to play. Think of the children! ...heh --chip On Mon, Jul 22, 2013 at 3:44 PM, Christopher Morrow <morrowc.lists@gmail.com
