Sigh.

It seems that the missing piece of the puzzle was this:  You can't
just add a default route (apparently).  You have to first add the
route to a specific interface.  It's not clear to me if this is
universally true, or just a consequence of something specific to my
setup (the server in question has multiple NICs).

The tl;dr is that it's necessary for me to do the following in order:

# ip -6 route add blah:blah::1 dev eno1
# ip -6 route add default via blah:blah::1

where blah:blah::1/64 is the address my datacenter gave me for the v6
gateway router.

I wish this had been more clearly laid out in the umpteen different
wikis and tutorials I've tried to follow.
