NTP unsynchronized

Hello.. I am trying to figure out why my router will not synchronize with an NTP server located an off-site facility; the NTP server is located at the Naval Observatory.

I have a Cisco 7200 VXR IOS 12.4

The clock and calendar both are set correctly.

Attached is my NTP configuration.

any other ideas??

NTP unsynchronized

ntp server 204.34.198.40

ntp server 192.5.41.40

ntp server 192.5.41.42

Have these worked before?

Can you try using the IP addresses of this list based on your country/region?

Re: NTP unsynchronized

Have you tried a different source other than ntp source Loopback0?

$ ntpdate 204.34.198.40

$ ntpdate 192.5.41.40

11 Feb 13:48:08 ntpdate[16826]: adjust time server 192.5.41.40 offset 0.001873 sec

$ ntpdate 192.5.41.42

$ ntpdate 192.5.41.42
