This counter tracks how many payload packets carrying the R-bit (sequence-number reset) have been received on this VPDN session from the peer. It tells an administrator that the remote end has reinitialized its sequencing at least once, which can be normal during setup but is a red flag if it recurs on an already-established session. For example, seeing this counter increment on a session that has been up for hours, without any corresponding reconnection event, would warrant checking the peer's tunnel stability.
