Oh, and I've found in the past that FreeBSD requires you to add the
interface name with a % sign after the v6 address when trying to
communicate via link-local:

#ping6 fe80::1%lo0

PING6(56=40+8+8 bytes) fe80::1%lo0 --> fe80::1%lo0
16 bytes from fe80::1%lo0, icmp_seq=0 hlim=64 time=0.224 ms
16 bytes from fe80::1%lo0, icmp_seq=1 hlim=64 time=0.131 ms
^C

...but when communicating to a global unique, you do not:

#ping6 2607:f118::b6

PING6(56=40+8+8 bytes) 2607:f118::b6 --> 2607:f118::b6
16 bytes from 2607:f118::b6, icmp_seq=0 hlim=64 time=0.234 ms
^C
