We have a new network we've built out with Mikrotik backhauls and
RB450G's at each tower. The towers are all connected to each other in a
ring, as shown below. Users off each AP are connecting over PPPOE
through a PPPOE concentrator (Cisco 2811) at the main tower. At the
Main Tower, we use a cisco 3560 switch instead of a Mikrotik router.
Main Tower : PPPOE concentrator, backhauls to Tower 1 and 3
Tower 1 : 2 AP's, sitemonitor, etc. BH's to main tower and tower 2.
Tower 2 : 2 AP's, sitemonitor, etc. BH's to tower 1 and tower 3.
Tower 3 : 2 AP's, sitemonitor, etc. BH's to tower 3 and main tower

Main Tower ----- Tower 3

Tower 1---------- Tower 2
We need to have private IP access from the main tower to each of the
devices for management, as well as have layer 2 ethernet from each
enduser device back to the PPPPOE concentrator. Currently we have
separate vlans from the main tower to tower 1 and tower 3. We manually
(working on scripting) swap the active vlan in case of an outage, but
that is not optimal. We've looked at the Mikrotik mesh, but it didn't
seem very reliable - breaks in the ring would take a long time to
"heal." We didn't spend much time on that though, so we could possibly
do more optimization to get that working well. Just curious what others
are using to get automatic fail-over and load sharing in this type of
scenario.
Thanks!
