Separate IKE SAs are IMHO the simplest way to go,
considering that
- I think that real-world MOBIKE deployments will not use this
kind of functionality anyway, or at least it will be extremely
rare in the near future.
- In many of those rare cases where different treatment is needed,
it can be handled adequately by creating several IKE SAs.
- This simplifies the protocol somewhat (e.g., no need to treat
those addresses differently for RR purposes).
- If the remaining cases (where the ability to have only a single
IKE SA would provide substantial user-visible benefits) become
more important e.g. five years from now, we can do something
about them then.
