[Pekka Savola <pekkas () netcore fi>]

Hi,

Some of you may remember about half a year - year ago, I asked for 
feedback (and got some) for an internet draft on MTU issues in the 
tunnels which are set up in the network.  This is a topic with pretty 
high operational relevance.

I've revised the draft again based on some really good feedback, and 
it's getting very near publication soon.

So, I'd like to solicit more comments (on- or off-list).  Please 
comment within about a week or so.

Abstract
   Tunneling techniques such as IP-in-IP when deployed in the middle of
   the network, typically between routers, have certain issues regarding
   how large packets can be handled: whether such packets would be
   fragmented and reassembled (and how), whether Path MTU Discovery
   would be used, or how this scenario could be operationally avoided.
   This memo justifies why this is a common, non-trivial problem, and
   goes on to describe the different solutions and their characteristics
   at some length.
