How to configure RADIUS to give IP address to a PPP client

I need to configure a RADIUS server, ACS if it's suported, to give a pre-defined IP address to a user connecting through PPP.


The NAS asks RADIUS for authentication then receives the accept or reject and some parameter that should tell the NAS the IP address the client will be assigned. (I guess it's this way)


Somebody knows which is this parameter and if it's this easy?


Thanks

Yes it also works fine. You may try this also.

Before configuring the RADIUS NAS-IP-Address Attribute Configurability feature, you must have configured the RADIUS servers or server groups and AAA method lists. To configure the RADIUS NAS-IP-Address Attribute Configurability feature, perform the following steps.

SUMMARY STEPS

1. enable

2. configure terminal

3. radius-server attribute 4 ip-address
