I have a machine (hostname
foo) with two wired network interfaces, eth0 and eth1. When I connect another host
bar to one of them (eth0), I can see in either one's NetworkManager that it's using "Link-Local Only" mode:
This works great—I can instantly communicate between the two hosts just with
ping foo.local or
However, as soon as I plug in a second host onto eth1,
bar.local become unreachable to each other, due to now having multiple overlapping 169.254.0.0/16 routes. How do I fix this permanently, such that I don't need to repeat some
ip incantations on each host every time I connect a host, and also minimize the amount of static IP configuration I have to do (I'd like to solve this in the most ZeroConfNetworking-ish way possible)?
