I have the following commands on my Cisco 3845 router running IOS version 12.2(24)T4:

ntp server 192.168.1.1 prefer

ntp server 192.168.1.2

ntp source loopback0

I see that the router is sending out NTP version 4; however, my NTP server is configured to accept only NTP version 3.  Anything other than version 3 will be dropped.

How do I go about to configure NTP on the Cisco IOS router to send out only version 3 and not version 4?

Thanks,
