Dear LSR WG,
I object on two basis ...
1)
The version -04 does not contain normative MUST that UPA shall only be
used to trigger invalidation when end to end encapsulation is used for
subject application(s). So as written is in fact quite undeployable in a
mixed vendor and legacy node(s) environment doing hop by hop routing. We
can't just hope that this is all about configuring the network in a
proper way.
above looks more like a comment that can easily be addressed by
additional text, which I'm willing to add, rather than an objection to
draft becoming a WG document. Please let me know if you think otherwise.
2)
The solution is too pragmatic ...
Isn't that a good thing, isn't it? :)
It does not look at the problem
holistically. Yes I still think the problem is worth solving but outside
of link state IGP doing UPA blast flooding everywhere domain wide even
if no nodes need that info. As discussed at length it could be done via
either BGP indirection or via PUB-SUB model (as proposed).
I don't object to solve this problem in BGP, or elsewhere. But given
that the problem we are trying to solve is created by the IGP
summarization and the ultimate source of the prefix reachability or
unreachibility comes from IGPs, having a solution in IGPs seems like a
natural choice.
thanks,
Peter
Regards,
Robert
