Hi all,

The remaining WGLC comment on this draft was that the mobility and 
multihoming part needed clarification and there was a potential problem 
with the TCP mode and reachability checks (if the check failed with the 
TCP mode, TCP connection would have been problematic to handle since it 
would continue re-transmissions).

To fix these issues, I updated the mobility section and now it's defined 
so that the mobility UPDATE packets are never sent on top of TCP. Also, 
I added an example (appendix A) of the signaling flows with mobility and 
multihoming to clarify how it works in practice.

There's also one small normative language change when TCP connection is 
created for ESP-TCP mode (section 4.2.); it used to say that if the TCP 
connection fails and only TCP mode is accepted, one MUST close the HIP 
association, but since one may want to try something else (not defined 
here), now it's only "SHOULD".

And then there's a bunch of editorial fixes.


Cheers,
Ari
