[c-nsp] clear ip pool

[Sebastian Ganschow]

Hi,

we've got our ciscos configured that ip pool configuration is derived 
from our radius servers.

In order to change the ip pool, I change the pool in the radius config. 
But our ciscos are still using the old ip pool. It seems like some 
caching issue.

Is there any way to let the cisco forget the pool information and get it 
again from the radius server?

Thanks in advance

Sebastian
