Depends what you mean by dynamic
in OSPF - a dynamic interface can be created within OSPF based on Network addition (including physical interfaces) - is this the dynamic interface you mean? If so you will need to move the physical interfaces to 'static' and add your path cost etc.
If you are talking about dial-in or style interfaces (VPN, PPPoE etc) - then you 'may' be able to do something dynamic with on-up scripts, but in the few instances that I require OSPF over these kind of dynamic interfaces, I've simply created a server binding so I can address it statically.
