Influencing/Programming RIBs can allow for a richer set of programming than
the actions defined in OFP today. I2RS is much closer to natural routing
behaviour with individual nodes running protocols.

I believe there is a future where both methods can live together,
especially with OpenFlow implementations supporting fall-through to normal
forwarding modes or multiple tables, etc.
