Babel over wireguard

[Ryan Whelan]

Are there any routing protocol implementations that do not depend on
multicast?  In my setup, 2 hosts will be able to route to one another over
2 different wg interfaces and I just need something to select whichever
interface has the least latency.  Anything like that exist? :D
