[c-nsp] BRAS for ATM DSLAMs

[Robert Hass]

Hi
I had to deploy BRAS for terminating ADSL subscribers. All DSLAM's and
access network is ATM based. Each user has their account at radius
server which provides settings for shaping (CAR) and other options.
BRAS is 7206VXR/NPE400/IOS 12.3 Enterprise Plus.

Is below configuration will work or I missed something ?

aaa authentication ppp RADDB group radius
aaa authorization network RADDB group radius
aaa accounting network RADDB start-stop group radius
