Hello to everybody. My name is Ezequiel and I’m seeking some info of very special but basic topics about routeros. I have read on this forum before to question and I have not found the answers, at least what I search.
What kind of Hardware I Need to manage about 3000 concurrent conections of ppp clients?
Must I use an x86 box or I’d have to use a RB hardware?
Can anybody give me any documentation about it? or or just answer according to their experience.
Thanks in advance.
By PPP I am amusing you are referring to PPPoE not PPTP VPN.
An RB1100-AHx2 ( Dual 1GHz PPC Chip ) can handle 300 easily but I suspect it cannot exceed 1000 PPPoE Terminations. I’ve not tried but I would expect the CCR to handle 3000 connections.
We terminate PPPoE at each location so as to spread the tunneling & QoS load over many devices. We have all local routers use a remote FreeRADIUS server for RADIUS replies. This works very well for us.
If you needed the routers at one location then you could have multiple routers on the network offering PPPoE termination and they will all pickup some connections with a somewhat random distribution. It is possible to load balance the PPPoE service if that is necessary for more scalability.
Here is a similar discussion:

Joshaven, thanks for your time and your response. We have probed a CCR 1036, and when it about to 2000 ppp terminations, some cores explodes and begin to appear tx and rx drops on the interfaces. We use freeradius and works very well for us too.
When you talk about multiples routers offering ppp terminations, you say them in the same segment?
Thank you very much.
PD: my english it’s no so good but i’m trying very hard to improve.
Yes in the same segment. As I understand the PPPoE service will pick up the requests somewhat evenly. Unlike DHCP you can have multiple PPPoE servers on one Layer 2 network. I have not ever had a need to do this so I don’t have experience with it but I have read quite a bit on MikroTik and PPPoE and I clearly remember reading that this worked.
I haven’t been able to find the info that I thought was best on the topic but here is some info:
