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. ------ Original Message ------ From: "Chuck McCown" <ch...@wbmfg.com> To: af@afmug.com Sent: 6/14/2016 10:27:33 AM Subject: Re: [AFMUG] Trango StrataPro Xi 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?

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).

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? -c
