There is no DHCP, it’s all static addresses, but there is an ARP table maintained at the router, and modern routers protect against ARP poisoning, meaning the same IP cannot have two mac addresses, and they will churn out errors. It’s also a security nightmare because many low level packet tracing tools will not work or give out false positives. I still don’t know how it’s working for you, because by all accounts, it shouldn’t.

Metric seems to cause Linux to mostly arp reply on one interface. Not a lot of switching. I can even plug in an Ethernet cable during a network transfer to speed it up. Linux treats ips as assigned to the host,so any interface can respond for packets sent to another interface (even if they have different ip addresses). There is some network weirdness that a security scanner might complain about, but it "works".
