[c-nsp] PPPoE passthrough

[Tseveendorj]

Hello,

I'm trying to configure PPPoE passthrough over Cisco 871 and PPPoE user 
contact to NAS. The topology looks like below

PPPoE user >> Cisco 871 >> Cisco 3825

The PPPoE already configured and working fine on Cisco 3825 but I do not 
know how the PPPoE user make PPPoE connection to Cisco 3825.
What kind of configuration I need to make ?


Note. I don't want the many NASs in my network. Because the showing 
dialed user on separated devices.

Sincerely,
Tseveen
