That's done in MSD drafts.
In the recently published isis draft we have also introduced MSD type flag
that would be used to signal different types of SID's: recirculated labels,
EL's, etc

Hey Gunter,

Good proposal however why do you only think about labels ?

Seriously if this is to move fwd let's add ability to signal also following

* ability to punt SR-MPLS to local CPU (slow path) when not handled in
hardware (per node basis)

* add signalling for number of SRv6 SRHs supported per node/per LC

* add signalling for depth per SRH and total of SIDs supported per node/per

* signal ability to punt to slow path or not for longer then support SRH
stack or number of SIDs in each SRH structure.

Heads-up… Happy to learn feedback and comments.

This draft is short and defines the attribute to use for BGP-LS to expose a
node RLD "Readable Label Depth" to a centralised controller (PCE/SDN).
