Another newbie question: Creating BGP prefixes in a filter

[Maria Matějka]

Hello,
Prefix aggregation is currently not supported. It's quite a lot of work to do it properly.
As a workaround, you may export these routes to an auxiliary kernel table, run an external script to maintain the aggregated route and learn the result back to BIRD. Or you can simply use the static protocol if your use case is simple enough.
