DDR only for ISDN?

[jalexander41]

Is DDR only used for ISDN connections? I have a router that I believe formerly had an ISDN connection on it. Now, it only has Frame-Relay. But, there is a dialer-list 1 protocol ip permit & dialer-list 1 protocol ipx permit statement on the router. Is this a "leftover" or is it still being used?

Dialer list commands are mostly used over Dial on-demand links like the ISDN.

Check where the dialer-group command is applied.

You are the best person who knows your setup and we cant say if it is a "leftover" or still being used.

There is no dialer-group command on this router. I inherited this router & it's configs.

Here is the config - some stuff was changed to protect the innocent!

Current configuration:

!

no service password-encryption

Yes, you can remove them.
