where to put PPPoE servers, on AP, other device, central?

[syadnom]

I have a single ‘branch’ of my network in place, something like this:

upstream internet>Core Router>Backhaul to tower(s)>tower router>AP>CPE
I have userman on the Core Router, and the tower router(s) have PPPoE server w/ radius>userman on core.

I have a target load of <=30 CPE on each AP. AP are RB411Ah w/ 680Mhz CPU. Tower router is RB493Ah w/ 680Mhz CPU. AP connect to tower router via switch .

Does it make sense to have PPPoE server on each AP? They would all connect to userman on the core router. With just 30 max clients per AP I think the AP has the RAM and CPU available to handle this, freeing up the tower router. The tower router may have a dozen different AP to route traffic for so I am thinking it is better to free those resources up.

Yes, it makes sense to have PPPoE server on each AP and then each AP authenticate against a single UserMan or Radius on the core router. That is exactly how I would do it.
