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
