PPPOE fowarding / LNS tunnel

ok, 1:30am blues here but ill try get words to what im attempting to do.

Currently we have a Layer2 network, with 11 towers, each with 2-10 AP’s
all connecting back into our LNS

what i want to do, for scalability and management reasons, is divide our Layer 2 network into 4, each segment would be its own layer2 bridged network.

however, i still want to use the one LNS (for QoS / IP management reasons)

so my question is: Is there a way, to do some form of pppoe request forwarding form a mik router to the LNS?

I’ll assume you are only running MikroTik routers in which case support for LAC functionality has not been added.

In which case try dumping all PPPoE users into a certain VLAN and then create a EoIP/VPLS tunnel between each aggregation router and the LNS. Use horizon bridging to stop users from different areas talking to each other.
