<p><font face="Arial"><i>Objective</i>: To understand how
to setup NTP on Cisco Routers.<br>
<i>Lab Equipment</i>: We will be using eRouter 1 &
eRouter 2 To
select eRouter 1 click
on the button "eRouter1" at the top of your screen. </font></p>

<p>1) Setup the connection between eRouter 1 (hostname <b>eRouter1</b>), and Router
2 (hostname <b>eRouter2</b>). eRouter 1 will have an IP address of 1.1.1.1 with a
255.255.255.0 subnet mask . </p>

2)
Configure NTP between eRouter1 and eRouter2. R1 should be a client
and learn the time from eRouter2. eRouter2 will be the master. On eRouter 2 set the
clock.</p>
