The point we were discussing was the fact that some implementations will reset the session timers / statistics. While the ISSU process may / should not affect the control and forwarding plane, in some implementations the timers for the session up-time and other statistics are reset . Should we address this as part of the Exit criteria for an ISSU process ?
