Hi David,

Touching on just one of your questions for now:

>Another possible issue with reusing fec0::/10 in RFC6724 is that it already has its own label but has a precedence of 1, the lowest. Does that work for your intended use?

Yes, I think that should be OK. MLAs are intended to be used only when no other types of IPv6 unicast addresses
are available. If a MANET node has somehow acquired a GUA/ULA it should prefer to use that instead of an MLA.

Thank you - Fred

Fred,

I still have concerns about whether a new scope is a good idea. But for now, I'll ask a couple of questions;

  1.  Will there be any need to use MANET local addresses URIs as IPv6 literals? Currently, there is no way to put a Zone ID in an IPv6 Literal URI.
  2.  Can a MANET host be part of more than one MANET zone? From the RFC4007 perspective, Zones other than Global have multiple instances.
Another possible issue with reusing fec0::/10 in RFC6724 is that it already has its own label but has a precedence of 1, the lowest. Does that work for your intended use? Yes, it can be changed, but it will take years to make happen.

Thanks

Hi, a new draft version is now posted (-03) that addresses comments raised on the list;

importantly, RFC5889 and RFC4007 are now also cited:
