Javier,

What is the output of 'show ntp associations"? The fact that sync_alarm is
up and that refid is 0.0.0.0 means that clock syncronization to an
external source was not made.

Also syncing won't take place if the difference is more than 128 seconds.
You may want to set your local router's time (set date) so that it is <128
secs from the time on 10.128.0.20. In addition, I am assuming you rebooted
the router, because otherwise the boot-server statement won't work.

Hope this helps.
