Thanks fro the note re: the broadcastdelay line. The %4 is the scopeID
-- I actually tested with and without this, the results being the same
in both cases. For command line ipv6 addressing, Windows requires the
scopeID to in order to resolve the link local address. I have a Linux
client that had to be configured similarly (%eth0).
