Introduction to Telnet</b></font></p>
<p><font face="Arial"><i>Objective</i>:
To become familiar with establishing a telnet session between two routers.<br>
<i>Lab Equipment</i>: We will be using eRouter 1 and
eRouter 2 for this lab. To select "eRouter 1" click on the Router
1 button on the top of the screen.</font></p>
<p><b><font color="#FF00FF">1</font>.</b> Connect To eRouter 1. For this lab we will
need to have the router accept telnet sessions and define the password we will
use for these telnet sessions. On eRouter 1 get to Configuration mode and set
the hostname to eRouter1. Then access the telnet lines. Each line in a router
represents an active telnet session it can support. For our routers we support 5
lines so the command you need to use is <font face="Terminal" size="2">line vty 0 4</font>. This will cover all 5
lines. </p>
