Hello,
I have been selected as the Routing Directorate QA reviewer for
draft-filsfils-spring-segment-routing-mpls-03.txt.
The Routing Directorate QA reviews are intended to be a support to
improve the quality of RTG Area documents as the pass through the IETF
process.
This is the QA review at
Loa, and all,
I have read the draft and your review on the Wiki page, and I think that your
question about domain-wide labels is worth detailed discussion.
In Section 2 Illustration, the draft says that:
- PE2 advertises (in the IGP) a host address 192.0.2.2/32 with its attached
node segment
Sasha,
SIDs are globally allocated and distributed. So, the answer to your question
about P1, P2, P3 and P4 knowledge of the SID representing PE2 is yes. Routers
within the domain must know the SID representing PE2 (e.g.: 102).
Now, when it comes to the dataplane, it has to be understood that
Stefano,
Lots of thanks for a prompt and detailed response.
If, as you say, the SID is just a global index into the local label space of
each LSR, then the statement PE1 pushes two label on the packet: the top one
is 102 (for SID=102) is grossly misleading IMO, and should be changed.
Regards,
Sasha,
I did NOT mean to imply that this discussion in the MPLS wg should
wait until the SPRING wg last call, on the contrary if the answer to
my question is that this a domain wide label, then it has to be brought
to the MPLS wg BEFORE this is adopted as a SPRING wg document.

Loa,
Seems we are in sync on this matter.

Sasha

Stefano,
I'm fine with that, but I guess that the SPRING wg chairs and/or the
rtg AD's need to make the consensus call on that.
