Hi Greg,

Section 4.4.1 still says “New state variables” for bfd.SessionType and the text still starts with “A number of state variables and their values are added…”, so I misinterpreted that as bfd.SessionType is being added as new state variable.

Please consider splitting this section in 2 parts for clarification e.g. 4.4.1 for New State Variables (bfd.SilentTail) and 4.4.2 for New State Variable Values (bfd.SessionType).

Hi Reshad,
I thought I've addressed them as per Carlos suggestion. Have I missed anything?

Regards, Greg

The changes for bfd.SessionType (it’s not a new state variable but uses what’s defined in RFC7880) weren’t made in the latest revision.

Greg, do you plan on addressing this soon? Or there’s no consensus on this topic yet?

    I believe this covers all points I've seen on the mailing list to date.

    Please push the updates.

    We'll have further discussion about the need for a registry in conjunction
    with the Yang module implications discussion.
