Not exactly. You don't need to advertise the RFC1918 to the OCA - just make
sure you advertise the CGN prefix to it, and make sure that the OCA's
default gateway knows how to reach the RFC1918 clients. So long as the

Thanks Dave, so my local OCA will listen to my BGP advertisements for RFC1918

Putting an OCA with bypass through the CGN with RFC1918 space will actually
work just fine. We (Netflix) don't formally support it because of the vast
number of non-standard CGN implementations out there, but if your clients
are in RFC1918 space and the next hop
An acceptable alternative would be a cheap muxponder to take say 2x40 + 2x10
and stuff it into a 100G. Fiberstore used to have one, but don't seem to carry
it anymore.

Getting issues from west-coast US clients trying to access services
like O365, Yahoo, GMail, etc. east-coast US doesn't seem to have the
same issue.
DNS servers are:
208.67.222.222
208.67.220.220
Switching to Google (8.8.8.8) fixes the issue.
Anyone else seeing this?

But I agree the commercials aren't as
FS has reasonable pricing on their amplification systems for DWDM.
The problem in the states is the dark fiber consolidation, so it's difficult to
find someone that'll sell it to you. Those that do, charge astronomically for
it.

The mux isn't the problem, it's that there aren't SFP28 optics commonly
available in C/DWDM wavelengths. Yet. If they were, well maybe...

Used Cisco Nexus 93180YC (oh, I guess New, sorry, it was on eBay, so I assumed

So then maybe that's the problem... not enough used 100G gear out there yet to
make it affordable... leaving 40G as the biggest
If it is passive, you could tell them it is for 10G but use it for 25G?

It wouldn't be hard to do any standard wavelength, really. They just need an

That’s because the DWDM solutions (at least the good ones, wisely) use
single-wavelength 100Ghz coherent light (like, you know, normal optics from the
rest of history), and do not play this 4x25g lane splitting game.
Unfortunately they are still quite expensive and physically large, smallest I

That's because, in active transport at least, 100G makes far more sense.
You may start seeing passive 25G WDM soon. Finisar have a DWDM tunable,
I believe.

Subject: Cheap switch with a couple 100G
I keep hearing how cheap 100G is
The argument should be 50G is cheaper than 40G.
Because serdes is 25G typically, you get 25, 50, 100 without gearboxes
and retimers, so less pincount, less thermal, higher density, lower
cost.
But BOM impact to pricing isn't high anyhow, unless we're talking
about massive port counts.

I keep hearing how cheap 100G is compared to 40G and it doesn't seem to hold
true. Prove me wrong.
Cisco Nexus and Arista both have switches with 48x 10G ports and 2x - 6x 40G
ports for under $1k. Swap those 40G for 100G and you're at $5k - $7k.
Am I missing some cheap switches with 100G?
