Hi Warren,
Thanks for the review.
In your example below
+--ro number-of-sessions (10)
+--ro number-of-sessions-up (2)
+--ro number-of-sessions-down (5)
+--ro number-of-sessions-admin-down (3)
There is a description on Page 37 of rev-16 of the draft, I can add to it as
follows, is this sufficient?
leaf number-of-sessions {
type yang:gauge32;
description "Number of BFD sessions.";
}
leaf number-of-sessions-up {
type yang:gauge32;
description "Number of BFD sessions currently in up state (as defined
in [RFC5880]).";
}
leaf number-of-sessions-down {
type yang:gauge32;
description "Number of BFD sessions currently in down or init state (as
defined in [RFC5880]).";
}
leaf number-of-sessions-admin-down {
type yang:gauge32;
description
"Number of BFD sessions currently in admin-down state (as defined in
[RFC5880]).";
}
I will fix the nits in the next rev.
Regards,
Reshad.

Don't panic, this should be an easy DISCUSS to clear, but I think it
important
for interoperability.
In multiple places, you have:
+--ro number-of-sessions?
+--ro number-of-sessions-up?
+--ro number-of-sessions-down?
+--ro number-of-sessions-admin-down?
I'm a little confused by the meaning of the counters, and didn't see them
clearly defined anywhere. Apologies if I missed it...
Are "number-of-sessions-admin-down" included in "number-of-sessions-down"?
Is 'number-of-sessions' always equal to 'number-of-sessions-up' +
'number-of-sessions-down', or is it always equal to 'number-of-sessions-up'
+
'number-of-sessions-down' + 'number-of-sessions-admin-down', or are there
other
cases?
E.g: I have created 10 sessions (because I have 10 interfaces). 5 of them
are
down because there is no peer, 3 of them I've configured to be down (admin
down), and so 2 of them are up.
What should be in each of:
number-of-sessions?
number-of-sessions-up?
number-of-sessions-down?
number-of-sessions-admin-down?

COMMENT:
----------------------------------------------------------------------
Thank you.
I also had a few minor nits:
Nits:
Section 1:
"The YANG modules in this document conform to the Network Management
Datastore
Architecture (NMDA) Network Management Datastore Architecture [RFC8342]. "
The
Department of Redundancy Department called and wants some of their words
back
please :-)
Section 2:
"Since BFD is used for liveliness detection of various forwarding
paths, there is no uniform key to identify a BFD session. So the BFD
data model is split in multiple YANG modules where each module
corresponds to one type of forwarding path."
I think this would be more readable as:
"... to identify a BFD session, and so the BFD..." (hey, I said it was a
nit)
