[dpdk-users] Question regarding packet availability

[Александр Киселев]

Hi.

You can use KNI interfaces to redirect the control plane traffic whether
it's a bgp or any other routing protocol traffic to the KNI while
forwarding data plane traffic using dpdk. It will allow your linux routing
daemon to receive route updates without having a dedicated physical
interface. After that you should find a way to redistribute the received
routes back to your dpdk forwarding engine. To do that you can use linux
netlink interface or quagga's FPM interface. The bird also has a API to
export routes, but I am not shure.
