... to follow up, from the documentation of bird 2:
string proto The name of the protocol which the route has been imported from. Read-only. What I am looking for is the opposite: string proto_to_or_destination_or_better_name The name of the protocol in which the filter or function is being called in. Allows to match on the destination. Example: if(proto_to_or_destination_or_better_name = "asn_1" and net ...) then accept; (obviously I made up the above description, but that's exactly what I'm looking for). Still curious on what others think about this. -- Sustainable and modern Infrastructures by ungleich.ch
