I agree. The only related thing is that you can run both on the same box, effectively creating another "hybrid" scenario, or as we like to call it, tri-brid. *)

Robert,

If topo information export is in scope (which I believe it is) and PBR route injection with nh recursion to rib (and thus connected routes) is in scope (which I'm quite sure it is) then yes, this is in scope.

Although I'm not sure what it has to do with OF /OF controllers? ;P

Hi,

This morning Scott mentioned that he would like to use IRS to shut down all protocols and just be able to write to RIB. Now James said that he would like to get a network topology as "every OpenFlow controller requires this"

Both connected together resulted in an idea of using multi-topology-routing where your base topology discovers physical link connectivity graph while other topologies could be programmed by external entities example: OF controllers or any other external to routers network intelligence oracles to deliver actual services ?

Would that be in scope of IRS effort ? If so what would be the proposed "write to RIB" set of protocols ? Would you support OF 1.3 even if one would be happy to lock such topologies only to software/programmable switching paths ?

Best rgs,
R.
