[j-nsp] B-RAS services

[Jason Warren]

I have a Cisco 7206VXR that I am wanting to replace with a Juniper MX80 (purchased as an MX5) or similar. The main core function is just Ethernet routing... but it also is acting as a B-RAS router for about 400 PPPoE sessions. I know the license cost on the MX80 for subscriber services is close to $15k.. which honestly puts it out of budget and pushes me back to a re-manufactured Cisco ASR.. Does anyone have some recommendations as to how to pull this off in a Juniper world? I was told by a VAR that on some of the larger Juniper chassis, this is not an issue as it is commonly included but unfortunately he was not positive which chassis this would be. 
My current thought is to maybe put a Cisco 7301 to service this function if nothing else...
Thank you in advance for any experience and advice anyone can offer!
