Yes, that's all there is.

In response to an offline challenge, I set up a Q&D on two 2501 routers.

R1 = ntp master
Manually configure time using the exec command clock set

The NTP clock synchronized to the system clock within a few seconds.

R2 = client ntp server (r1 address )
Watching the NTP debugs I see the following:

Lots of activity immediately.

Show NTP status reveals that the reference time is that of the NTP master
 R1 )

But the system clock on the NTP client ( show clock ) has not updated even
after several minutes.

Show NTP stat and show NTP association both reveal that the clock is
unsynchronized

As I said, perhaps after layer two is configured, NTP should be the first
task completed. Apparently it takes several minutes for the system clock to
be updated from the NTP clock.

Is that all there is to configuring NTP?
