As a WISP can I ask what is the advantages/ disadvantages of having PPPoE server at each tower when running
(2) L2 Bridged
(3) Both OSPF + L2 Bridged
Sounds good the advantage but by having the PPPoE at the tower does it mean that traffic must transverse the network to PPPoE server before Queue limits are applied?Main advantage is spreading your risk to have a pppoe server at every pop. Second advantage is that not one router is doing all queues/firewall/natting for all clients.
