    LGTM, perhaps we can use VPCID % 255 to get a value that is less than 255 but greater
than 0?
    @remibergsma @fborn @wilderrodrigues Do you think using a static/fixed value can cause
any issue (maybe in future)?

> The current code uses the VPC ID as VRID, but it doesn't have to be unique per VPC, but
for NIC. So, we can simply use 51, as the KeepaliveD suggests.
> # arbitary unique number 0..255 # used to differentiate multiple instances of vrrpd #
running on the same NIC (and hence same socket). virtual_router_id 51
