Hey Guys,

Hope you all are doing well.

I have a simple three switches set up. Lets call them A,B and C . A is
connected to B and C , B is connected to A and C and C is connected to A
and B.

A,B,C are running quagga as a routing daemon and are able to exchange
the routing information.

Now I install OVS on A,B,C and connect them to the external controller.

But after connecting this, A,B,C seem to not to be exchanging routing
information . This is expected because now the switch needs rules which
are to be added by the controller so that it could forward the BGP
packets generated by Quagga.

Now how do I make quagga work with A,B,C when it is connected to an
external controller?

Dear Shivram,

you are right, openvswitch in itself cannot behave like a router and routing packets have to be forwarded to quagga

in this paper we propose a solution for "Hybrid IP/SDN networking" that combines openvswitch and quagga:

“Hybrid IP/SDN networking: open implementation and experiment management tools”, IEEE Trans. on Network and Service Management, accepted for publication, published on line Dec 2015
http://arxiv.org/abs/1505.03579 (doi:10.1109/TNSM.2015.2507622)

the implementation of the solution is open source, you can find additional information on http://netgroup.uniroma2.it/OSHI/

ciao
Stefano



Thanks,
Shivram
