This is the erratum of whose arrival I speculated on this list on June 16th.

There is a degree of urgency about it.  The I-D in question is mpls-base-yang, currently in IETF Last Call, which is a Normative dependency of bfd-yang which is a Normative dependency for a small mountain of I-D which have been waiting a year or so (e.g.  ospf-yang).

I suspect that the technically perfect solution would involve a YANG union, choice or some such structure but as I said in my Last Call comment I can live with a label that contains such as 'address' encompassing such as 'label' in the context of forwarding.  I take labels to mean what labels mean rather than what I might find in a work of reference.

The following errata report has been submitted for RFC8349,
"A YANG Data Model for Routing Management (NMDA Version)".

You may review the report below and at:
https://www.rfc-editor.org/errata/eid6251

--------------------------------------
Type: Technical
Reported by: Tarek Saad <tsaad@juniper.net>

Section: 7

Original Text
-------------
The RPC "active-route" is used to retrieve the active route in a RIB.
RFC8349 defined two AFIs (v4/v6).

draft-ietf-mpls-base-yang is defining a new RIB AFI for MPLS as per section 3 in RFC8349.

The RPC has a "MUST" statement that all RIBs must augment input
parameters with a leaf named 'destination-address'.

For MPLS RIB, it makes sense to augment with leaf named 'local-label' since MPLS routes are identified by MPLS label.

We ask to make the following change:

OLD:
           action active-route {
             description
               "Return the active RIB route that is used for the
                destination address.

                Address-family-specific modules MUST augment input
                parameters with a leaf named 'destination-address'.";

Corrected Text
--------------
NEW:
           action active-route {
             description
               "Return the active RIB route that is used for the
                destination address.

                Address-family-specific modules MUST augment input
                parameters with a suitable leaf that identifies the route.";
