Hi Victor, Thanks very much for your response. Do you mean set next-hop on BGP with Quagga or similar applications through other NIC (not DPDK managed)? I looked at DPVS , which uses KNI to redirect traffic to Kernel so we can use Quagga or advertise VIP. Do you think it's a better solution or implement ARP in the DPDK application directly? Thanks.
