Configure IP pool from radius server

Question

Hi, all
My ADSL system's using a ERX-700 (juniper) as a BRAS and 7206 for backup.
Everything is alright except assigning name of pool to BRAS.
ERX-700 use frame-pool attr to provide pool name instead of addr-pool attr as 7206.
IOS can unsupport this attr but I can't configure both attr on radius.
Can you help to overcome this problem
Thanks a lot.

This is a radius issue. It does depends on the AAA server you're using how to configure both NASes independently.
For instance, if you would be using NavisRadius product as AAA server to configure which attributes to send back per NAS is really piece of cake:
1) First, you have you to define how to identify separately both NASes, either by IP, technology, by checking the calling-station-id, or whatever.
Supposing you do use IP, which maybe is easier, you do have to define a clients file, for instance:
10.0.0.1 secret_key ERX700
10.0.0.2 secret_key2 Cisco7200
10.0.0.3 secret_key3 AS5800
2) Depending on who's sending the request define what to do next and what attributes send back. With NavisRadius you make this thru a Policy Flow, which is like a set of instructions to configure it, either manually or thru a GUI. Thru this set you could do for instance:
checkClientClass Method-Type="Branch"
Branch-Case = "Cisco7200\tsetIPAdressPoolA"
Branch-Case = "ERX700\tsetIPforERX"
Branch-Case = "AS5800\tsetIpsecService"
Branch-Case = "*\tUnknownClient"
Branch-SelectMode = "KEY"
Branch-SearchKey = "${client.Client-Class}"
3) And finally depending on the tag used go to another method which sends the needed attributes back to the NAS or do whatever you want to do depending on the case.
This is a very brief example, since the product is really flexible and allows many other possibilities, like getting the IP pools from another server, etc.
Good luck!
