Okay, I tried the case of all of NICs on a host and confirmed it
works fine.

The results of ifconfig and netstat are the following. These are by
another configuration from one I sent in the previous email, but the
symptom is still reproducible:

When doing "ping6 2001:db8:1::" from box-A, the source address becomes
2001:db8:1::6 (this is correct) and a link-local address on msk0 on
box-B replies.
