Getting the log will be the hardest part as the BRAS is owned by the incumbent 
and they are rather hard to communicate with. If we had control of the BRAS 
the problem would have probably been solved by now...

Here is an example filter that is being used in production on the Cisco BRAS, 
but is completely ignored on the ERX. Also the Ascend-Client-Primary-DNS is 
being ignored, we have to explicitely add the Unisphere-Primary-Dns attribute 
for those users who connect through the ERX. Again please remember that the 
Ascend attributes below are automatically being converted into abinary type by 
our radius server.
