I'm trying to load balance my pppoe tunnels in multiples pppoes servers.
Actually I'm using 2 x RB450G to end tunnels, each ends tunnels in his broadcast domain, but I guess if it is possible tu put more than one pppoe server in the same broadcast domain and let's the protocol decide on wich server end the tunnel, based on availability and other thinks that I don't know at time ?...

Any clue?

Yes, it is possible to put multiple PPPoE AC's onto the same subnet. The client will issue its PADI and receive PADO responses from both AC's, but will connect only to the server who's reply it sees first (assuming the PADO service-name's are the same).

Can I assume that with this scenario I'll get all the sessions "well balanced" on the AC's ?
Can I scale this solution with multiples AC's on the same net?, let's say 5 or 6 AC's ?

I think will be nice a feature on router os to configure a random delay on PADo responses. This feature exist ?

Best regards,

If you make multiple pppoe servers with the same hardware configuration (let's say 5 RB1000), they will balance perfectly between all of them because the less used will have a faster PAD0 response.
Tried and it works perfectly. No additional configuration needed.

router os delays PADO responses according the load on the device ? this sounds nice.
