[Netext] PMIPv6 local routing - update of the PS

[liebsch at nw.neclab.eu (Marco Liebsch)]

Folks,

according to the feedback the current version of the localized routing 
problem
statement seems to cover almost all aspects which are relevant for the
NetExt work on localized routing.
Two remaining aspects have been addressed, which should be considered in
an update of the draft to be in line with the WG's view. These are as 
follows:

*Localized Routing between a PMIP attached MN and a regular IPv6 node*:
This was a comment from Carlos and addresses the type of nodes
RFC5213 mentions in a few paragraphs about local routing. We could clarify
this offline and better text about what RFC5213 describes and how this
impacts NetExt work on localized routing will go into an update of the PS.

*Consideration of IPv4*:
This is a good point made by Sangjin and the PS should cover an analysis
of relevant issues with IPv4 for PMIPv6 localized routing. There is 
valuable
early work available, such as draft-jeong-netlmm-pmipv6-roreq-01 and
draft-wu-netext-pmipv6-ipv4-ro-ps-00. I think it makes sense to send a
separate mail to collect different aspects of IPv4 problems in PMIPv6
localized routing and to discuss individual issues we need to cover in
the PS.
