RR-group is a local feature applied to inbound vpnv4 updates, which does
not involve any ORF capabilities to push the filtering to the peers. So
the behaviour you're seeing is expected. rr-group has been around for
quite a bit longer than any orf capability..

I've not seen rr-group being used yet, rather conventional filters in
case RRs need to be partitioned, as you've suggested..
