Hi Les,
Thanks a lot for your review and comments.
This new MSD is a per-node capability just like ERLD-MSD, mainly because it
represents how many MPLS labels the node can read, and it is not related with
the links.
And the description in this draft you mentioned is written taking example by
RFC9088(section 4. Advertising ERLD Using IS-IS).
I'll explicitly state the scope of the new MSD in the next version.
Best Regards,
Yao

Yao –
Both RFC 8476(OSPF) and RFC 8491(IS-IS) define MSD advertisements with per-link
scope and per-node scope.
Your draft only states:
“If a router has multiple interfaces with different capabilities of
reading the maximum label stack depth, the router MUST advertise the
smallest value found across all its interfaces.”
This suggests that you intend only to advertise a per-node capability – but as
you don’t explicitly state that – and you don’t provide a reason why a per link
capability isn’t applicable, I am unclear as to what your intentions are here.
Could you clarify whether you intend to support both per link and per node
capability – and if not why not?
Thanx.
Les

Hi All,
A new version of draft-liu-lsr-mpls-inspection-msd has just been uploaded.
In this document, a new type of MSD is defined to reflect the Readable Label
Depth(RLD), which helps in the MPLS MNA solution.
In this version, the main update is that some description is added to explain
why a new MSD is preferred instead of the ERLD-MSD.
Currently this new MSD is called Base MPLS Inspection MSD, it may be changed to
a more straightforward name like RLD-MSD based on the description in the MNA
architecture/solution document.
Your comments and suggestions are more than welcome!
Thanks,
Yao
