Currently there is no other way to filter on prefixes which don't have a community. You can use the ssv output to make the filtering easier or you tag the prefixes with a different community (first set community on all routes and then delete community again from those where you set the other community). Adding a 'not' option to community matching should be possible. I will look into that after 6.6 is out. -- :wq Claudio
