Agreed. :-)

My requirement for this - both at the ISP level and the IXP route server
level is :

 - I can using my own script, rebuild filters every day, against an RPSL
 - I want, without resetting sessions, to replay the prefixes available
over a session and test them against the new session.

On Cisco/Juniper, I do this exactly as Wolfgang describes, i.e. change the
filter config and then clear soft the session.  The router then makes a
route-refresh call to the peer, has the peer replay the prefixes, and my
new filters become enforced.
