interpretation of SA bundle.
I may be missing something, but I don't know how to interpret a proposal
of SA bundle exchanged on phase 2.
Node A sends a proposal including AH tunnel mode followed by ESP tunnel
mode. In this case, we should interpreted to be created IP payload by
using this SA,
1. [outer IP][AH][ESP][inner IP][ULP]
2. [outer IP][ESP][AH][inner IP][ULP]
3. [outer IP][AH][inner IP][ESP][inner IP'][ULP]
4. [outer IP][ESP][inner IP][AH][inner IP'][ULP]
Which is right ?
Another case, Node A sends a proposal including AH transport mode followed
by ESP tunnel mode.
1. [outer IP][AH][ESP][inner IP][ULP]
2. [outer IP][ESP][inner IP][AH][ULP]
I think there is not these rules of interpretation in any drafts.
