Some different router options Here are three, each w/ different levels =
of capability:
Option #1 - CISCO3845 (3RU tall)
1x CISCO3845
2x MEM3800-512D
2x HWIC-1GE-SFP
1x GLC-SX-MM
This will provide 4x GbE ports, which will fill the minimum need as =
described below.
Option #2 - CISCO7204VXR (3RU tall)
1x CISCO7204VXR
1x NPE-G2
1x C7200-I/O-GE+E
2x PA-GE
2x PWR-7200-AC
This will provide 6x GbE ports (though 3x will be fiber only - this is a =
good option in terms of performance, so I still put it out there, as it =
may be possible to work around). Performance wise, this is about 4x as =
powerful as the 3845 above. If we need an in-between option, replace =
the NPE-G2 with an NPE-G1 - the G1 is about 2x as powerful as the 3845.
Option #3 - Cat6500 (4RU tall)
1x WS-C6503-E
2x PWR-1400-AC
2x PEM-20A-AC
1x WS-SUP720-3BXL
1x WS-X6516-GE-TX
The maximum performance option, the 6503-E here is capable of =
40Gbps/slot (as configured, the 16 port GbE card gets 8Gbps of =
throughput). If DC power is needed, you can change to the 7603-S =
chassis, which is the same form factor, just available with high-output =
DC power (which would be needed here).
For all 3 options, DC power is available if needed.

Subject: Recommendations for router with routed copper gig-e ports?
All:
=20
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.
=20
My problem on the redesign is I want to provide routed, copper gig-e =
ports
at a reasonable price per port.
=20
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.
=20
So number of routed, copper gig-e ports at each tower would be:
=20
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)
=20
Does anyone have any suggestions?
=20
Sincerely,
=20
