Multiple WDS interfaces on PTMP access points are causing packet duplication to the point where performance and latency is suffering. Routing would be ideal, however it would require changing settings on 500+ client routers already setup for PPPoE.
eliminate the packet duplication, but maintain Layer2 connectivity to authenticate PPPoE clients.
Crude outline, but basically at the main location we have our upstream bandwidth going to the R1 router, the it goes through the switch to various Mikrotik PPPoE Access Concentrators (AC2). Each AP comes into it's own port on the Access Concentrator. We have some PTP links for our high traffic sites, other sites are fed through a PTMP setup with WDS bridging. This has become a problem because of the increasing number of interfaces on the bridge is causing packet duplication, resulting in loss of throughput and increased latency.
Is there any way I can accomplish my objective through VLANs, or using a less attractive protocol like EoIP to tunnel the traffic back to the AC?
I was thinking of creating (on AP2) a unique vlan on ether1 and bridging it with a single wds interface. Then creating the other end of that VLAN on the Access Concentrator and create a PPPoE server on the VLAN interface. The question I guess is, can a VLAN interface be unnumbered, and does this sound feasible?
Routing would definitely be my preference, but this company has committed to PPPoE for authentication and accounting and there's no segmentation between network distribution and access layers. In many cases there are clients and other Access Points connecting through the same wireless interface.
