To register a new route, we need prefix, prefix length, home AS. The
rest is helpfull, like contact information for when things are broken,
or might break. If the AS is already known, we have policy for it, so
you don't need to bother figuring out which AS and ENSS to route
through as you did with each NACR. If new AS keep popping up, you can
define an AS macro such as:
and then specify that each new AS falls into the AS macro and so get
the policy treatment for the AS macro.

I'm surprised your trouble ticketing system doesn't support a "next
action timer" that allows you to get notification after some time
period, like when the new circuit is supposed to be turned up, or when
the routing reconfiguration is supposed to have been completed so you
can then check connectivity.

I agree on the security note. It should be more secure. Then again
accepting route advertisements with no validation whatsoever isn't
very secure either.

First - the current spec is RIPE-181.
AS 690 has about as complex a set of policies as anyone I can imagine.
RIPE-181 can handle our import policy just fine. We've suggested some
minor syntax changes that would substantially reduce the number of
lines required to express this (without defining a few thousand macros
to accomplish this), but the current syntax does provide the needed
flexibility. Our export policy cannot be expressed in RIPE-181
because some of our export policy is AS path based. An AS path
extension has already been proposed (or at least batted around on the
rps mailing list).

Thanks for sharing your insights on this topic.
btw- I correected the Cc (which I botched in the first place) from
prs at isi.edu to rps at isi.edu.
