The driver only builds the IPvlan L3 mode port and attaches the container to the interface. Route distribution throughout a cluster is beyond the initial implementation of this single host scoped driver. In L3 mode, the Docker host is very similar to a router starting new networks in the container. They are on networks that the upstream network will not know about without route distribution. For those curious how IPvlan L3 will fit into container networking, see the following examples.\n\nIPvlan L3 mode drops all broadcast and multicast traffic. This reason alone makes IPvlan L3 mode a prime candidate for those looking for massive scale and predictable network integrations. It is predictable and in turn will lead to greater uptimes because there is no bridging involved. Bridging loops have been responsible for high profile outages that can be hard to pinpoint depending on the size of the failure domain. This is due to the cascading nature of BPDUs (Bridge Port Data Units) that are flooded throughout a broadcast domain (VLAN) to find and block topology loops. Eliminating bridging domains, or at the least, keeping them isolated to a pair of ToRs (top of rack switches) will reduce hard to troubleshoot bridging instabilities. IPvlan L2 modes is well suited for isolated VLANs only trunked into a pair of ToRs that can provide a loop-free non-blocking fabric. The next step further is to route at the edge via IPvlan L3 mode that reduces a failure domain to a local host only.\n\nL3 mode needs to be on a separate subnet as the default namespace since it requires a netlink route in the default namespace pointing to the IPvlan parent interface. The parent interface used in this example is eth0 and it is on the subnet 192.168.1.0/24. Notice the docker network is not on the same subnet as eth0. Unlike IPvlan l2 modes, different subnets/networks can ping one another as long as they share the same parent interface -o parent=.\n\nBounded code example (external data; do not execute automatically):\n```console\n$$ ip a show eth0\n3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000\n    link/ether 00:50:56:39:45:2e brd ff:ff:ff:ff:ff:ff\n    inet 192.168.1.250/24 brd 192.168.1.255 scope global eth0\n``` …\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
