Recommendations for router with routed copper gig-e ports?

Mon Feb 15 01:47:50 UTC 2010

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!

I hope this helps

Subject: Recommendations for router with routed copper gig-e ports?

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,
