[Netext] First Problem Statement about Localized Routing in PMIPv6 submitted

Hi:
Our draft on local routing optimization has already addressed this issue in the section 8. The URL link for this internet draft can be found in:
http://tools.ietf.org/html/draft-wu-netext-local-ro-00
The two possible scenarios are:
a.MN is IPv4 enabled and receives IPv4 home address 
b.and the transport network between the LMA and the MAG is an IPv4 network.
Also to my point, the Localized routing as addressed in the PS document is quite similar to Local routing as described in the RFC5213 and we don't need to restrict the correspondent node as a mobile node, in this sense, Shall we align with the definition of local routing and have reference to the RFC5213 in this current PS document.

Regards!

Hi Marco,

Thanks for developing the RO PS document. It seems that the RO application
scenarios in the current document does not explicitly mention IPv4
support cases.
When a PMIP6 domain supports IPv4, the IPv4 support scenario of RO may be
divided into following possible subcases.

(1) a MN and a CN IPv4 home address mobility
(2) a MN and a CN belong to different MAGs and both MAGs support IPv4 transport
to the same LMA
(3) a MN and a CN belong to different MAGs and the MAGs support
different IP version
transport to the same LMA

I think that it is worthwhile to investigate each subcase so as to
decide which subcase
should be included in the scope and/or whether there is any issue to
be resolved.

Regards,
Sangjin
