Hi,
I'll repeat here my comment that I gave on the mic.
1. I believe the point of the draft is to say that you should not use RAO end-to-end across the Internet.
yes, that is one of the points the draft is trying to make.
From our conversation, I believe your specific suggestion would be that section 3.1 is generalized to say e2e RAO is problematic, whether for new e2e application/protocol or for existing application/protocol (while it currently only explicitly mentions this for new application/protocol). Right?
If you have a closely controlled environment, RAO is okey, provided that you know what you are doing
Again, from conversation, you'd like section 2 to make that point irrespective of whether we're talking about existing or (potentially new) protocol/application. Right?
(and this part is what the document is trying to tell, describe the more or less well-knwon problems with RAO). Yet, to me the message is a bit fuzzy and unclear.
I think addressing the previous points would probably make things clearer. Feel free to propose additional specific suggestions.
2. IPv6 hop-by-hop options have the same problems, I guess.
For the sake of closing the RAO issue asap, I liked the idea of just focusing on RAO, but if the WG wants to kill the "hop-by-hop option" bird at the same time, I suppose we could. Opinions?
Thanks
Francois
Cheers,
Jukka

Hello,
The Routing, Transport and Internet area directors have agreed to move the
work on Router Alert option (that started in Routing Area) into the Internet
Area.
Therefore, we would appreciate feedback from this list on the new version
of draft-rahman-rtg-router-alert-considerations.
Thank you

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
Title : IP Router Alert Considerations and Usage
Author(s) : F. Le Faucheur
Filename : draft-rahman-rtg-router-alert-considerations-02.txt
Pages : 18
Date : 2009-07-03
The IP Router Alert Option is an IP option that alerts transit
routers to more closely examine the contents of an IP packet. RSVP,
PGM, IGMP/MLD and MRD are some of the protocols which make use of the
IP Router Alert option. This document discusses security aspects,
common practices and usage guidelines around the use of the current
IP Router Alert option. Specifically, it provides recommendations on
the use of Router Alert by new protocols, discusses controlled
environments where existing protocols depending on Router Alert can
be used effectively and discusses protection approaches for Service
Providers. Finally it provides brief guidelines for Router Alert
implementation on routers.
