Yes that's exactly what I had on mind, based on community associated with the
route -the resulting term would be applied only to filters on interfaces
represented by the community.
However that would mean to redo the whole thing from vrf filters to interface
filters.
-which btw would be great as with per interface filters and specified direction
of filtering the PFEs handling traffic in opposite direction would not need to
do the extra work.
-since as it is right now PFEs handling traffic (doing lookup) in opposite
direction, than one for which the filter was actually intended for, have to
churn through the filter for every lookup -so these PFEs are burning cycles
unnecessarily.
