Someone can help me to configure two routers using NTP MASTER and NTP
SERVER to coordinate their times???

Javier,

In Wisconsin, U.S.A (Central Daylight Time), I use:

On core router that can communicate with an authoritative time source:

--- cut ---
clock timezone CST -6
clock summer-time CDT recurring
ntp source TokenRing0/2
ntp master
ntp update-calendar
ntp server 10.1.1.1
--- cut ---

The 10.1.1.1 address would be the address of your authoritative time
source.  If you don't have one you can leave that line out and make
sure the time on the router is set "correctly".  If you do this then
your master should be a router with a calendar (battery clock) like a
4x00 or 7x00.  If not then neither router will have the correct time
but at least they'll be the same.

On the remote router:
--- cut ---
clock timezone CST -6
clock summer-time CDT recurring
ntp server 10.1.1.2
--- cut ---

10.1.1.2 would be the address of the "TokenRing0/2" interface
from the core router above (you use whatever interface you want,
probably the one your routers will likely be communicating over but
not necessary).

After a while you'll see the routers have added the command
"ntp clock-period 17179960" (your number will vary).  Just do
a "write mem".  I believe this is the router calculating the
amount it's clock drifts from the authoritative time source.

I hope this helps.
