How do I configure NTP on My Cisco Router?  How do I find a reliable NTP Server?

Currently I have no NTP server specified on my Cisco Router.  I have the timezone and daylight savings time configured but no NTP server.  Should I have an NTP server?  If so, how do I go about choosing one?  Would I configure this on all my cisco devices or just my router connecting to my ISP?  Thanks

Yes, you should use NTP as it makes log timestamps usable.

Here are two I commonly use:

Washington, DC: U.S. Naval Observatory
192.5.41.41: tock.usno.navy.mil
192.5.41.40: tick.usno.navy.mil

You typically want to choose a time server that is close geographically and is reliable.

Set the router to use stratum 1 Internet time servers (like above) and then you can point your other devices to the router for their time.

Thanks.  So once I configure NTP on my Router, I just point my other devices (ASA's, VPN Concentrators, Switches, etc) to that router that I configured NTP on?  Will not using NTP slow down a network?

Yes, correct, you can point your other devices to the router.

NTP will not speed up or slow down the network.  It is simply to keep the time on the device as accurate as possible.
