I agree mainly with the document draft-ietf-mext-nemo-pd.
It is good and needed to dynamically assign a Mobile Network Prefix to
the NEMO-enabled Mobile Router.
However, here are a couple of missing points.
One missing point is about how will the Mobile Router configure its
default route on the home link? I thought Prefix Delegation would bring
DHCP in the picture and would allow MR to synthesize a default route
even though RAs are absent. But I now realize that a DHCPv6-PD
implementation (and std?) does not allow a router (MR) to synthesize its
default route (neither RA does, nor DHCPv6-nonPD does).
=> I think the MR can easily act as a host on its egress interface and
configure its default/next hop router that way. Of course the other
alternative is to use routing protocols, but I think using ND should be
sufficient.
