Hi,
On the 1st point, this is why we have WG item #4 (exchange
policies
between the MN and the HA).
For your 2nd point, I don't think it's reasonable to say
"it is
**necessary** for the CN to communicate with MN in RO
mode". It's not a
requirement, but it should be a feature ! I think it's nice
not to
require all traffic to transit via the HA when the MN is on
the home
link. In any case, this point is discussed in
draft-ietf-monami6-mip6-analysis-00.txt. (the draft has been
submitted,
it should be announced before the end of the week).
Thierry.
PS: could all people on this list make sure to set a
meaningful subject
line ?
Thierry.
