Hello!

I have one concentrator running mikrotik, i use PPPoE protocol for authenticating users.
So i want to add another identical machine, so i have two concentrators,
if first fails other is getting his role.
Is it posible with Mikrotik? do i need to use VRRP or what?
Please give me some advice

Thanks again!

yes you can do that. best if you have some radius server for auth (or have doubled secrets on both RB's) and then just set the second RB to ping first one, when ping fails turn on pppoe

Hello,

Thanks for the quick answer!

I need little more info, yes i'm using freeradius on linux.
So i need VRRP or not?

I can use same pool of IP addresses on second AC, i only need to route it to both AC-s?
So when first fails, second is taking his job.
I need to use script: Secondary AC is pinging all the time first, and when first fails, secondary AC is activating his PPPoE service, right?

Thanks in advance!

What about having both PPPoE running in the same network together?
Freeradius assigns dinamically the ip addresses with radippool..
and if one of the two pppoe dies, the other one will take all the job while you fix your problem

Hello!

I don't use radius to assign dynamic ip addresses, the AC is doing that.
If both AC-s are on the network, they will work together, some connections will be on the first, some on the second right? and when
one of them failed, all users will reconnect to second? that's what you mean?

Thanks!

Exactly. Remember to assign different ip pools to the pppoe servers otherwise you might experience some ip conflicts.
And, if you can, use the same hardware configuration for both the pppoe, this way you will have a good load balance between them
