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/
