Hi, Alexander and all

 

Thanks for the info and comments for LI.<= /p>

After reading RFC 3924 and “LI from ETSI”= ;, my feeling is that the scope of LI for satellite networking will be pret= ty big and easy to be confusing, so I would think there should have a spera= te draft talking about it. The current draft will add reference to it.

 

Comments?

Brian, Stewart and all,

RFC 2804  notwithstanding, IETF has published RFC 3924  on Cisco LI Architectu= re.

This is not a formal contradiction, since 3924 has been published as I= nformational.

Can this be used as a precedent?

The IETF position on LI is not exactly that it's anath= ema, but that we will not standardise *any* intercept techniques, legal or = otherwise. RFC 2804.
