I think the point is that Layer3 scales better.
For something simple you can keep it simple, but as the network gets
larger you always end up wanting Layer3 so as an ISP you might as well
just start where you're going to end up anyway.
It's also safer to keep the broadcast domain small.

I am missing something here. What is wrong with using a $6000
microwave as a piece of long CAT 5? Point A to Point B extending your
reach.
Why complicate it with layer 3?

Switch? If people do layer 2 over $6,000+ microwave for backbone links
between two POPs, that is a really bad idea in my opinion. WISPs love
to build layer 2 clusterfucks because a lot of small ones start with
basically no OSPF or BGP knowledge.
Show me a real router platform that is in common use that supports 2.5
Gbps SFP (not SFP+ on a rate limited port).

There are such things as 2.5 Gbps SFPs used for fiber channel storage
array applications (example: Cisco MDS9000) but you will not see them
used in ethernet speaking routers/switches.

Check with John, but I thought he said something about a 2.5Gbps

So I’m checking out the new Trango StrataPro data sheets… The Xi
model appears to do 4Gbps full-duplex.. but no 10G SFP+.. So I’d
have to use all three SFPs, and one copper gig to get it?
Other notes: it appears they’re keying it up.. so you get to pay
extra to unlock capacity to 1100Mbps and again to unlock max
capacity to 2200Mbps.
Oh and if you want AES-256, you get to pay again. The 1MB packet
buffer.. seems low.
Anybody else have any thoughts? Anybody got one yet?
