[c-nsp] PPPoE termination on ASR9K without SE linecards

[Brian Turnbow]

Hi George

I have always been told that TR cards do not support bng that you need for
pppoe on asr.
Same for the old trident cards.
And even  if they did you would be severely limited in qos scaling. (if
you need really  high qos scaling you should go tomahawk btw)
There are some cisco live presentations deep diving the architecture and I
remember some with the "not supported" for  bng as a feature for tr cards.
Also on the cisco support forums the articles on bng by xander all cite
the use of SE linecards for LC termination.

You can do it on rsp as the 9001 supports bng just fine.

regards

Brian
