That appears to be correct. The vmxnet3 DPDK PMD looks like it does not support adding or deleting a MAC address. I never attempted to add support for secondary MAC addresses to the native VPP vxmnet3 driver either. So VRRP is not able to manage secondary MAC addresses on vmxnet3 devices.
Adding a VRRP virtual MAC address to a device as a secondary MAC address is primarily intended to avoid putting the device in promiscuous mode. Since the vmxnet3 DPDK does not support secondary MAC addresses, you can try setting the device in promiscuous mode. I haven't tested that in a while, but it worked the last time I tried it. -Matt On Mon, Jun 8, 2020 at 11:36 AM steven luong via lists.fd.io <sluong= cisco....@lists.fd.io> wrote: > Vmxnet3 is a paravirtualized device.
