NTPv2. This is what I see in a router with "debug ntp packet detail" configured with "ntp master 2":
Dec 15 20:21:55.694: NTP message received from 10.10.10.254 on interface 'FastEthernet0/0' (10.10.10.1): Dec 15 20:21:55.694: NTP Header: Leap = 00, Version = 2, Mode = 3, Stratum = 3, Poll Interval = 6, Precision = -20, Root Delay = 0.28, Root Dispersion = 0.742, refid = 10.10.10.1, Last update reftime = 3501433252.2768737782, Originated time = 3501433313.2990220735, Received time = 3501433313.2992084671, Transmit time = 3501433315.2995658084.

The version = 2 field must mean NTPv2. I see that field = 4 with a router as a client.

I hope ntp version 4, as that's the current version as of 2004. ntp version 2 dates back to 1989. NTP stratum 2 is completely different.
