Nice, thanks.

> In our policies we explicitly allow prefixes we want in BGP and deny everything else by default so it's not really an issue.  In my experience that is pretty much standard practice for BGP...otherwise you could accidentally leak all sorts of nasty things.


Externally of course we do. I'm not in love with the way iBGP was set up here, but they apparently wanted "all routes everything" kind of internal sharing. Obviously however it's much better to share "everything I will route a packet to", of which fxp0 doesn't qualify.
