Rate-limit from PPP client to PPP client

Hello all,

I have PPPoE clients connecting to a RB3011.
They are rate-limited using the rate-limit variable in the PPP profile.
The shaping works great between one client and the outside (if you disable fast-track), but it seems it’s not effective between 2 PPPoE clients.

Am I missing something or is there a limitation on the queuing mechanism that would explain this ?

Thank you

David
