I find that em0 gets an IPv6 link local address but bridge0 does not = (via net.inet6.ip6.auto_linklocal). I did some googling and it seems = that this is a deliberate policy decision, and unfortunately you can't = change it on a per interface basis :) It would be nice if I could suppress automatic link local for em0 and = enable it on bridge0 rather than having to delete & add them manually. Also, does anyone have a code snippet handy for generating link local = addresses? My google-fu was unable to find a description..
