Just a note that moving filters from pipes to bgp protocols have several
other consequences, some positive, some negative:
1) You see just what is accepted and you cannot directly see rejected routes
(but they can be seen in log, if enabled).
2) Rejected routes does not eat memory.
3) If you change filters and call 'configure', the appropriate protocol
si restarted. If it is a pipe, it causes a route flap (routes propagated
through the pipe a withdrawn and immediately repropagated), if it is a bgp
protocol, it also causes a session flap (BGP session is restarted).
Possible workaround is to use 'configure soft' command (which ignores
changes related to filters) and then 'reload' command for protocols with
changed filters. We will change the behavior of 'configure' command to
do this automatically in next versions.
