1 question:


When S1 in another area receives such LSA, it then can learn that
   prefix Lt1 is associated with node T1, check the ELC, ERLD, or MSD
   value according to its necessity, and construct the right label stack
   at the ingress node S1 for the traffic destined to Lt1.

How is S1 going to know the "ELC, ERLD, or MSD" of  node T1?
I guess, T1 will need to send an AS-scoped router info LSA?

If so, should T1 be ASBR as to be able to send this AS-scoped LSA?
I guess it was needed before as to enforce  the ABR to create the T4 LSAs,
so that others can learn which ABR to use to reach T4, but I guess
it's not needed anymore when this draft is implemented.

Regards,
Dirk

This begins a two week adoption poll for the subject draft. Please send your comments to this list before 12:00 AM UTC on Thursday, February 28th, 2019.

All authors have responded to the IPR poll and there is one <https://datatracker.ietf.org/ipr/search/?submit=draft&id=draft-wang-lsr-ospf-prefix-originator-ext>  https://datatracker.ietf.org/ipr/search/?submit=draft&id=draft-wang-lsr-ospf-prefix-originator-ext
It is listed multiple times but references the same CN201810650141.

Thanks,
