Of course it is a complitly different approach.
OSPF is just an example... in instance you could obtain informations
about your network topology and from a Netflow external db and
"manually" (of course you don't have to do it manually but it is the
smart module that you wrote on your controller that does it...)
distribute custom routing rules based on your own metric on the switches.
I know it sounds so commercial but...in theory (and also practicaly)
with SDN everything you've in mind becomes possible. This is because
there aren't fixed schemas given by a specific protocol. With SDN you
can write your own protocols!

Hey Joel!
Thanks a lot for the reply, really appreciate it.
If i may ask: With OpenFlow a network engineer could from now on pick
which features he or she wants to enable and which not. So i could for
example only use OSPF. Now, how does one configure OSPF on a
controller? I mean in a pure SDN environment where all the
intelligence is in the controller.. Do you configure OSPF on the
controller? And is it like configuring OSPF on a router?
Thanks again,
Farhad.

There are people who believe it is practical to control an entire
large itnerprise or operator internal network with a single
cluster of SDN controllers. In that view, there is on need for
IS-IS/OSPF/EIGRP.
Most other folks expect that there wills till be IGPs in use,
among SDN controllers and between SDN controllers and conventional
routers.

*Subject:* [openflow-discuss] SDN & Routing Protocols
Hey folks,
Another newbee question: Will the future SDN networks have
routing protocols such as OSPF, EIGRP? I apologize if these
questions are "simple" but i really cant find this information
anywhere.. I know that hybrid will be able to support the
old protocols and i know about routeflow.
What i specifically want to know is: Will future SDN networks
need OSPF/EIGRP? Does SDN in its pure form mean the end of
OSPF/EIGRP?
Kind Regards,
