=====================
We share the view that for many networks only some abstraction of
the actual routing policy should/can be published in the IRR.
Right now we are abstracting it to a very essential minimum.
The most important and helpful use of the IRR is to publish what a
network will announce to peers and upstream.
We are providing that by means of the as-set 'AS-PLAN-B' and
route-set 'RS-PLAN-B' which we have and will been keeping up to
date all the time.
