Call back RAS

Unanswered Question
Oct 10th, 2007

Dear All,

I have a router Cisco 2610 for remote call, the user authentication dial up to connect network use Tacac.

The user account can already make call back to other router, but not with my Cisco 2610.

every time user dial, he directly connected with no call back.

Could anyone help me to make it work as I want ?

Here is the sotfware image:

IOS (tm) C2600 Software (C2600-IS56I-M), Version 12.0(10), RELEASE SOFTWARE (fc1)

and here is the configuration:

Hi Stephen,

Here are the choises available for the command "PPP callback....."

1. accept Accept a callback request

2. initiate Initiate callback without PPP callback negotiation

3. request Request a callback

Callback permit is not available.

Thank and regards,

Coi

Sorry

Didn't see you're using IOS 12.0

The command was introduced later...

You wrote that your client can do callback at another router.

Ist it using the same AAA Server?

If not. Are Callback (Dialup client specifies callback number) and TACACS+ PPP settings (PPP IP, PPP Multilink, PPP LCP) the same?

Hi Stephan,

I am using the same AAA server, and tacas+PPP setting PPP IP and PPP LCP.

Thanks,

Coi
