Hello Nanog,
Our company are constantly growing and we're looking for a 30k+ subscribers BRAS, does the community have a sugestion?
Thank you!
Is a monolithic 30k+ a requirement, or would 3-4 10K boxes(or other
similar combo) be usable?
Cisco ASR 1004/6
Alcatel Lucent 7750 SR12 with MSA card
a WHOLE bunch of others 
Juniper MX
Alcatel-Lucent 7750SR

I'm pretty sure this would get expensive for 30k+.
Perhaps try Walmart?
Cisco ASR1006 or ASR1013
Cisco ASR9006, ASR9010, ASR9904, ASR9912 or ASR9922
Juniper MX240, MX480, MX960, MX2010 or MX2020
Alcatel-Lucent 7750SR
Smaller models allow you to distribute workload into smaller chunks.
Bigger models do the opposite, but scale faster.

We just bought a couple of MX480s for B-RAS to replace some aging Cisco 7206/VXRs. Not racked or powered yet (showed up yesterday), but hope to have one of them online for testing next week.
Our initial test with an eval MX-80 verified functionality.
Has anyone in the BRAS world paid attention to bufferbloat yet?
I like that Juniper finally dropped further development of the dedicate
BRAS code. It had become annoying.
Mark.
The Walmart ones cost less upfront, but their support sucks. This often leads to sags in performance, especially from the view of the average eyeball network user, which results in personal discomfort when senior management determines that the best way to resolve the issue is to bring in some external consultants to really strip the system down and get hands-on with optimizing heap sizes.
I have a related question. What functionality defines BRAS?
I do not think I have any BRAS in my network, but I am not sure

BRAS functionality would normally be large scale DHCP or PPPoE customer
termination handled by RADIUS for authentication and policy management.
hey,

subscribers BRAS, does the community have a sugestion?
I can tell only good stories about Alcatel 7750-SR. Extensive BNG feature set (both v4 and v6) and very stable platform.

If you have budget constraints, try getting 2 x ASR1004, else ASR1006 with dual RP would take care of your needs.

You can try Ericsson SSR or SE.
