Understanding IPVLAN interfaces

An alternative to MacVLAN is IPVLAN. IPVLAN comes in two flavors. The first is L2 mode, which operates very similarly to MacVLAN with the exception of how MAC addresses are assigned. With IPVLAN mode, all logical IP interfaces use the same MAC address. This allows you to keep the parent NIC out of promiscuous mode and also prevents you from running into any possible NIC or switch port MAC limitations. The second mode is IPVLAN layer 3. In layer 3 mode, IPVLAN acts like a router and forwards unicast packets in and out of IPVLAN connected networks. In this recipe, we'll cover the basic IPVLAN networking construct to get an idea of how it works and how it can be implemented.
