Filtering out a attribute conditionally

[Mike O'Connor]

Hi All

I have a problem with my Cisco 7301's where I apply a address pool via a
Cisco-AVPair (for each wholesale ISP customer) and the wholesale ISP
supplies a Framed-IP-Address at the same time, the connection is kicked
by the cisco.

Is there any way of adding or removing the ip_pool bases on a rule ?

Could Freeradius 2 do this ?

Thanks
Mike
