<font face="Arial" size="2">Multiple dialer interfaces may be
configured on a router. Each dialer interface is the complete
configuration for a destination. The
</font><font face="Courier New" size="2"><b>interface dialer </b></font><font face="Arial" size="2"> command
creates a dialer interface and enters interface configuration mode.
<img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"></font></p>
<p><font face="Arial" size="2">To configure the dialer interface,
perform the following tasks:
<ol>
<li>Configure one or more dialer
interfaces with all the basic DDR commands:
<ul>
<li>IP address</li>
<li>Encapsulation type and authentication</li>
<li>Idle-timer </li>
<li>Dialer-group for interesting traffic</li></ul>
<li>Configure a </font><font face="Courier New" size="2"><b>dialer string</b></font><font face="Arial" size="2"> and </font>
<font face="Courier New" size="2"><b>dialer remote-name</b></font><font face="Arial" size="2"> to specify the
remote router name and phone number to dial it. The </font>
<font face="Courier New" size="2"><b>dialer pool</b></font><font face="Arial" size="2">
associates this logical interface with a pool of physical interfaces. </li>
<li>Configure the physical interfaces and assign them to a dialer pool
using the </font><font face="Courier New" size="2"><b>dialer pool-member</b></font><font face="Arial" size="2"> command.

dialer pools by using multiple </font><font face="Courier New" size="2">
<b>dialer pool-member</b></font><font face="Arial" size="2"> commands. If more than
one physical interface exists in the pool, use the </font>
<font face="Courier New" size="2"><b>priority</b></font><font face="Arial" size="2"> option of
the </font><font face="Courier New" size="2"><b>dialer pool-member</b></font><font face="Arial" size="2"> command to set the priority of the interface
within a dialer pool. If multiple calls need to be placed and only one
interface is available, then the dialer pool with the highest priority
is the one that dials out. </font></p>
