BRAS/BNG Suggestion

Good morning,
Could you suggest some vendors of BRAS/BNG for PPPoE termination?
We have more than 20.000 users.

In my short list there are already Juniper, Cisco and NOKIA/ALU.
Do you have any other honorable brand or good experiences?

Redback used to be popular - I believe they got picked up by Ericsson.


Ericsson SSR 8010 is good platform. We have been using it since last 3 years with no major issues.

Havn't tested IPv6 though.

I'd steer clear at a small scale like 20k subscribers. In my experience, Ericsson as an organisation just aren't set up to deal with a company that want to buy a couple of boxes, install and run them themselves, and call support when something breaks - it's all about multi-month PoCs and fully-managed rollouts at incumbent-telco scale. Think 20M subs, not 20k.


I've heard Redback aren't so good anymore. We are very happy with Cisco
(ASR1000s) and Juniper (MX480s) for this function.


Our current deployment uses several Alcatel SR 7750 boxes - we pair these
with MX960 and MX2020 for CGNAT for several hundred thousand customers.
Alcatel and Juniper have been a rock solid combination so far.





2nded, I tried for months to get Ericsson to get us a quote and sort
us out with a solution as I'd used their kit and liked it in the past.

Exactly as Tim said, they just didn't seem interested if you're not
after a big $$ solution.

We went with ASR1k as cisco came to the party on price and we were already
using 7200 at the time. No complaints.


Yes, it seems that our use case it's not the right one for Ericsson.

I was told by some high up people in Ericsson several years ago that their
target for the Redback range is the top dozen telco's and they are not
really interested in smaller customers. It's a shame, because the Redback in
many ways is still superior to other offerings IMHO. To the OP's question -

1. The Nokia 7750 is a good option, but you would likely need the larger
7750-SR or 7750-e over the 7750-a series as the "a" does not have the MS-ISA
card option that allows access to several key BNG functions. Likely outside
of budget once spares etc are taken into account

2. Cisco ASR1K, likely this will do what you need, the advantage if the 1K
range is it's just a big CPU based box, so you don't need add on cards to do
anything fancy. There is also affordable support and an active grey market
option available (2x asr1006-esp40).

3. A virtual offering from Juniper (VMX) or Cisco might work for you.
Nokia's offering is a bit too new.

I would choose option 2 with option 3 as a backup if you want to get things
going quickly. Unless money is not an option then option 1 (2x 7750-sr7 or

The Nokia is the rebranded Alcatel 7750. The syntax is funky, but it's a great bras.
