BNG base RP or LC is best

[anas.abdullkarim]

helllo, i have rotuer A9K with ios 6.6.3 , 

the have two card : 
RP: RSP440-SE 

LC :A9K-36x10GE-TR,

I confirm it as BNG (PPPOE / Radius auth) ,  but that two choose to create a PPPOE session  

1- on physical port(1G/10G) so the process of PPPOE will be on Lincecard (LC)

2- on Bundle-ether(BE) Port's so the process of PPPOE will be on Lincecard (RP)

what is your suggestion about my case ? my target is  largest number of session with QoS per session

for BNG deployment, it is recommended to use the -SE line cards due to the scale.

you can review this document for LC based subscriber features
