CURRENT_MEETING_REPORT_
Reported by Philip Almquist/Consultant
RREQ Minutes
Shortly before the St. Louis meeting, the second Internet Draft version
of the Router Requirements specification was released. Except for a few
open issues (described below), the technical content of the document is
fairly well set. Extensive editorial work remains to be done.
On the first day of the meeting, the Chair conducted a brief
``Introduction to Router Requirements'' session for first-time attendees
and anyone else who was interested. After that, the Working Group dove
into four half days of meetings.
Three of the four sessions were devoted to fine-tuning the draft.
Particular attention was paid to chapters 3 (Link Layer), 4 (Internet
Layer Protocols), 9 (Miscellaneous Application Layer Protocols), and 10
(Operations and Maintenance). We also discussed what still needed to be
done to complete the draft. Items identified included:
o Chapter 8 (Network Management) still needs to be written.
o Much of chapter 9 (Miscellaneous Application Protocols) still needs
to be written.
o Coverage of security-related topics needs to be extended.
o There should be additional discussion sections providing
implementation hints and explaining the rationale behind some of
the requirements.
o Several smaller sections need to be written or revised.
o As mentioned above, extensive editorial work is still required.
Volunteers were solicited to do the necessary work. The issue of
variable length subnet masks was also raised. Since the IETF Working
Group on this topic is still not underway, we tentatively decided that
Router Requirements would have to partially skirt this issue, though we
will say more than the current draft does.
The remaining session was devoted to discussion of three important and
interrelated issues: 1
1. Route choice -- how a router chooses which route to use to use for
a packet when the router has several routes (learned from different
routing domains) to the packet's destination.
2. Route leaking -- how a router which is in multiple routing domains
decides whether a route learned in one routing domain ought to be
advertised into other routing domains.
3. Route filtering -- how a router decides whether to disbelieve
certain routes from certain sources.
Each of these issues has two components:
1. Constraints -- what must (or must not) be done to avoid undesirable
phenomena such as routing loops and black holes?
2. Controls -- what sorts of configuration options does a network
manager need to be able to do to make routing work in moderately
complex parts of the Internet?
The Working Group was not able to reach any consensus on these issues,
but will continue to try to address them in the time before the IETF
meeting in Atlanta in July. However, several Working Group members also
participated in a productive Border Gateway Protocol (BGP) Working Group
session which addressed issues specific to route leaking between BGP and
OSPF.
Frank Solensky deserves considerable commendation for diligently noting
all of the changes to the draft which were agreed to during the course
of the meeting.
