I thought that I had commented on this Last Call but perhaps not.

The English is quirky, e.g. mixed singular and plural, missing definite 
and indefinite articles and such like but I do not think that that 
impairs my understanding.

Contacts needs https:

The examples use the line folding convention which needs a reference 
else our XML reviewers will complain

What makes life more difficult is the terminology which I find 
inconsistent e.g. tag, route tag, administrative tag - are these the 
same or different? and if different, which is the YANG leaf tag?  RIP 
has a tag which I think different but perhaps confusing to those who are 
familiar with it.

The Introduction sounds very generic in its talk of routing protocols 
but I think that it promises more than it delivers; the YANG description 
seem to do the same in places. The reality is that in some places only 
static routes are augmented; what about dynamic routes?  And where they 
are augmented then I think that that needs calling out.  In a similar 
vein, I think the first paragraph of s.3 wrong.

'The following tree snapshot' looks like an extract to me, not a snapshot.

I have commented in the past about active route and I still find it 
tautological.
