Hi Linhua,
First of all, you need to bind an IP address on NIC that DPDK manages. You
can look at https://github.com/victordetoni/dpdk-l3fwd-acl this project and
copy arp (line 644) and ip stack (line 2024). After that, you can set as
next-hop on bgp the ip address that dpdk manages.
Maybe it's not clear yet, but dpdk is a framework that allows you to create
your own network apps. Search on google bgp projects that supports bgp,
quagga etc.
