I would strongly suggest it.. as it appears that most people seem to
have an advertise all, accept none policy in regards to the route
This doesn't fit with our experience on the IXes. We have generally
found most people are running basically an advertise all, accept all
(except obvious badness) policy on the IXes.
Taking off my IX hat and plopping on my CDN hat, I'd observe that during
the Olympics we peaked at around 1.5Gb/s delivery into APE, and about
1Gb/s into WIX. That's on routers with no bilaterals over APE - clearly
somebody is listening to the route servers.
I'd be interested to see any evidence of a
widespread practice of overly
strict inbound filtering of routes from APE/WIX/etc, as it would
encourage us to do more bilateral peering.
The StreamingNet routers attached to the exchanges only peer with the
route servers (not for any particular reason, more that until this
discussion started, it hadn't occurred to me to seek bilats - I
hadn't perceived they were necessary). It maybe that folks are allowing
the StreamingNet prefixes and dropping everything else, but that sounds
a little far fetched.
There are some peers who won't take longer than a /24, and others who
have a restricted announce policy (particularly in Wellington), but I
haven't heard of anybody announcing but not learning. If you are
advertising prefixes into the route servers that are not getting out to
other peers, then it would be worthwhile checking the route server
looking glasses and ensuring that it's not the filters on the route
servers dropping your announcements.
