Show inverted filter result

[Matej Vadnjal]

Hi list.

Is there an easy way to list routes that do NOT match filter?

I can do "show route filter f_myfilter" to list routes that would match 
filter.

I'm hoping for something like "show route filter !f_myfilter" to list 
routes that would be rejected.

I'd like to display routes rejected in a pipe protocol between two 
routing tables so I still have all routes that are rejected by filter in 
BIRD.


Kind regards
