Route filter ROS7 OSPF

RouterOS Forwarding Protocols
1

Could use a little help with route filters for OSPF: I’d like to block advertising networks on some but not all OSPF interfaces. I’m not seeing a way to apply filters per interface on ROS7. Help?

Specific case is I want to only allow some routes to be advertised over a zerotier connection and let other routes take the normal path.

Thanks in advance
