I had noticed the lsps vs lsps-state, mentioned it at last BFD WG meeting and have been in touch with the teas-yang authors.

I hadn't noticed that mpls:enabled had been removed. I'll have to go through all MPLS-related items in the BFD yang.

Regards,
Reshad.

    Yes bfd-yang.  Sometimes I would like to be wrong.

    When I look at this I-D, I see that it references
         /rt:routing/mpls:mpls/mpls:interface/mpls:config/mpls:enabled
    In 2018, the MPLS WG removed that /config from the mpls-base-yang so
    this would seem to be no longer valid. What needs changing to rectify
    this I have not explored.

    The I-D has
          augment "/te:te/te:lsps-state/te:lsp"
    which I no longer see in  draft-ietf-teas-yang-te - the -state has gone.
    Again, I have not explored the ramifications of this.

    MPLS WG has a new base-yang out this week which differentiates between
    an IP route with a MPLS next hop and a MPLS route with no IP, the latter
    forming a new, mpls Address Family.  I would think that the latter is
    not catered for by BFD but it would be nice to be wrong
