When it is away from home it is fully a Host on the egress

this way.


=>   Ok that doesn't make any sense to me.

Well, let me rephrase as the RFC text puts it: when the MR is at home it
joins the all-routers multicast address, otherwise it joins the
all-hosts address.  ND spec says similar.  Similarly, when MR at home it
can send RAs on the egress, if away it MUST NOT send RAs on it.  It must
always send RAs on the ingress.  This is to make sure MR doesn't break
the Internet routing.

Does this sound better?

=>  I thought we were discussing the specific issue of how to solve this
problem in _this_WG_ as I mentioned in my first email. I know what the RFC
says and I wouldn't have done it this way but given this, I don't know how
else you can solve it _here_.

I am open to solve it here and I have suggestion :

- make DHCPv6-PD-NEMO assign a default route to the Mobile Router at
  home.

What do you think?

I also followed advice and went asking to DHC WG.  I got redirected to 
MIF soon-Charter DHCP options route table, and got mentioned 
draft-ietf-v6ops-ipv6-cpe-router req W-3 talking DHCPv6-PD and default 
route.

=> Then we better wait for this draft to move forward.
