Introduction

This configuration is for a dial-on-demand routing (DDR) setup. The user needs to ping an AppleTalk node located at a remote site in order to bring up the link. Use the dialer idle-timeout number interface BRI0 command in order to control how long the link stays up without interesting traffic. In this example, the Cisco 2501 dials the Cisco AS5200 based on the AppleTalk static routes and dialer maps that have been configured. This allows the AppleTalk ping packets to reach the Ethernet node of the Cisco AS5200.

Note: IP has not been configured in this example.

Verify

Use this section to confirm that your configuration works properly.

The Output Interpreter Tool ( registered customers only) (OIT) supports certain show commands. Use the OIT to view an analysis of show command output.

show apple zone—In order to see the AppleTalk zones
show apple route— In order to see the routing entries in the routing table

Show Command Sample Output

This is the output of the show dialer map command for both routers:

isdn-1:
 Static dialer map appletalk 4615.106 name isdn2-2 (5557528) on BRI0

 isdn2-2:
 Static dialer map appletalk 4615.34 name isdn-1 () on Serial0:23

This is the output of the show apple zone and show apple route commands for the Cisco 2501:
