I can't get Cisco router synchronized with the ntp server.

Can you ping the ntp server (I can't ping it from my end)
Are the addresses valid or just not responding to pings
If yes
Is there any firewall policy blocking port 123
I'm assuming you have
Stratum 16?
That's too many generations -
Try linking to one of these Open Access Stratum servers closest to you.
http://support.ntp.org/bin/view/Servers/StratumOneTimeServers
I use these 2
*~128.9.176.30
+~216.218.254.202

Ok
I see your ntp servers have private IPs.
In your question, you typed
ntp server 195.168.200.195
ntp server 195.168.200.95
Both addresses are public addresses
In your reply, you typed private addresses
192.168.200.95 and 192.168.200.195
Which is the correct IP?
Looks like you may have typed the wrong ip address when configuring the ntp on your router.
