I actually think the 912 is different then the 904 and 906, as I was discouraged from buying the 912, and I REALLY wanted the extra ports. That's not to say that the 904/906 doesn't have the same problems. I use it for a router with a bunch of connected networks, DHCP relay, and BGP. Other then the below mentioned DHCP-relay bug, and an FTP command bug (which was also quickly fixed) they have served us well.

The OS906 may be different than the OS912, but be warned that I had major issues with OS912 relating to LDP and OSPF. Constant crashes of both LDP and OSPF made the device totally unusable. We had to ship all 20 back to them. It was really messy. This was about 6 months ago, and their code may have been fixed, so YMMV.

I have found the MRV OS906 (6 port 10/100/1000/SFP + Eth OBM) to be a very cost effective and an extremely flexible device. It's a linux based device with a router shell but all forwarding is done in hardware (ASICs). It has a very flexible implementation of many L2 features (QnQ, inner or outer tag swapping, eth OAM, ERP) but also sports standard routing switch features and protocols like BGP, OSPF, even IS-IS!
The cost of the device is 1/4 of a 3560G (etc).
MRV's support has been very good. We found a bug in the DHCP-Relay function where it would not broadcast back to a client that discovered/requested with the broadcast bit set. They provided a new spin of code with the fix within days!

All:
I'm involved in a project where we are cutting over a WISP from being a single broadcast domain into the grownup real world of routing between tower nodes. Of course the equipment is all Mikrotik and the single broadcast domain was easy to implement, so that's why it was done this way.
My problem on the redesign is I want to provide routed, copper gig-e ports at a reasonable price per port.
My thought is to provide one copper gig-e port for all of the APs at a tower and a copper gig-e port for each backhaul to other towers (typically 2 to 4). On the core nodes, I want to have one fiber gig-e port for the internet connection. BGP would be implemented on the routers that connect to the internet. OSPF would be implemented on all of the backhaul ports.
So number of routed, copper gig-e ports at each tower would be:
1 - AP network (need suggestion for cost effective gig-e switch)
2 to 4 - back haul ports
1 - internet port (on one out of every 4 towers or so) (and most likely fiber instead of copper)
Does anyone have any suggestions?
Sincerely,
Lorell Hathcock
