There's nothing special required on the Babel side to use wireguard.
However, since Wireguard doesn't do this automatically, you need to
manually set up link-local IPv6 addresses on both sides of the wireguard
tunnel. I usually just configure fe80::1/64 on one side, and fe80::2/64
on the other side of the tunnel, with appropriate AllowedIP configs to
go with them (either ::/0, or fe80::/64).
