This is regarding the comment I made yesterday during draft-liu-rtgwg-yang-vrrp, Xufeng rightfully stated that this was a question which had to be addressed for all YANG models.
I have attached Juergen’s email on this topic. Regards, Reshad.

Once you have more than one application trying to reset counters you get into trouble. Note this RFC 6991 (lifted from RFC 2578): Counters have no defined 'initial' value, and thus, a single value of a counter has (in general) no information content. Applications have to read a counter C at time t0 and then again at time t1 and then calculate the difference C(t1) - C(t0). This allows applications to obtain statistics at different time granularities without stepping on each other. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/> _______________________________________________ Rtg-yang-coord mailing list [email protected] https://www.ietf.org/mailman/listinfo/rtg-yang-coord
