Now that I read this, I must say that I do not understand the
description at all. What does 'i.e. the path name of a corresponding
interface data node on the containing node reminiscent of data type
if-ref defined in RFC 7223.' tell me? If the intention here is that it
is unique across a network I think this should be stated more clearly,
that is, not as a sub-thought in a sentence trying to explain why
if-ref can't be used. And then, what is a 'network'?
And looking at the whole choice, the other options are not unique
either. For unnumbered-id, the description says "will correspond to
the ifIndex value of the interface" which very likely will clash for
different nodes. Also IP adresses may not always be unique 'across a
network'. So why do we have this "unique across a network" requirement
for the interface-name case? That is, we can't we use
/js
PS: Why is interface-name marked 'ro' in the tree diagram? It looks
like a config true node.
