I think I do understand. I personally haven't used VLAN's much, and multiple IPs bound to a single netdev mostly so far as they belong to a different segment.
In the scenario: $ip addr add 192.168.0.1/24 dev lan $ip addr add 192.168.0.2/24 dev lan I had difficulties finding programs that allow you to control the source IP. 'ping' is one, and the only one I needed then. But this compares very close to what I want to do with J1939 on CAN. > So far you missed that step entirely.
