Seamless Interworking of SDN and IP

SDN-IP helps migrate your network to SDN • Allows an SDN network to seamlessly connect to rest of the Internet using BGP• Peers with BGP speakers and creates OpenFlow paths in the network in response to

received routes from the peers • Allows scaling of SDN control plane by interconnecting smaller SDN networks
