Sam,

Since the current generation of IPsec specs recommends ESP-NULL over 
AH, any reference to 2402 is very questionable for any new WG 
document, e.g., LISP documents. Also, MD5 is not an algorithm that I 
think most SECDIR folks would recommend at this point in  time. What 
motivates this retro security fetish?

Also, what does "static" AH mean re authentication data, key lifetime, etc.?

I am not volunteering to enter the LIPS WG debate. However, I will 
volunteer to review and comment on LISP documents when they come up 
for IETF LC. The security ADs may choose to pay attention to such 
comments, which might result in a DISCUSS at that stage. Presumably 
the authors would like to avoid that :-).

Steve
