Re: [Int-area] I-D Action: draft-ietf-intarea-tunnels-03.txt

[Joe Touch <[e-mail]>]

Hi, all,

This update incorporates all pending changes, notably from detailed
reviews and discussions with Fred Templin, Lucy Yong, Toerless Eckert,
and Tom Herbert.

There's still a bit to do - notably to wrangle out what we want to say
regarding other RFCs in Section 5. This, and the doc's evolution,
suggest that it might be useful to consider shifting the intended track
from Informational to BCP or beyond, depending on whether we need to be
higher than BCP to "update" some of the problems outlined with
standards-track docs (most notably RFC2003).

NOTE: A brief summary will be presented by the chairs in Berlin, but I
will not be attending. Please use the list as the primary venue for
discussion.

I am currently hoping we can decide how to proceed on this doc in the
next few months so we can either remove or complete any "pending"
sections and get to WGLC early this fall.

Joe

Summary of changes:
- now "updates" 4459 (informational too)
- revised MTU terminology based on list discussions (all MTUs indicate
"link" payload sizes)
- revised figures to indicate proximity of ingress/egress "interfaces"
to nodes
- moved Appendix A to new Section 3.6, as outer/inner fragmentation
issue is core
- revised Sec 4.2 (was 4.1) to explain why two different frag algs are
presented
    - one is implicit in all hosts/forwarders, irrespective of link
technology
    - one is contained "within" the link technology of a tunnel
- updated recommendations throughout section 5

Summary of additions:
- Sec 4.1 on the variety of MTU values
- Sec 4.12 on multipoint tunnels
- Sec 5.4 on diagnostics- Sec 5.5.1 on GUE
- Sec 5.5.15 on RTGWG-DT-ENCAP
- Security Considerations text on inner/outer tunnel vulnerabilities
- Recommendation text for Sec 5.5.3 on RFC2003 (IPv4 in IPv4)
