How did you get your ASR1002 to link at 100M?
I've been pulling my hair out trying to get that to happen, with no

It doesn't.

We have a fairly similar design for our Metro Ethernet network.
Our primary method of protection is STP(MST). I've been thinking about
this, and I can't come up with a reason why we even really need an IGP
down to the edge PE devices? Since it's all layer2 - the core
switch/routers see
as a reference, no need for an IGP down there?

I second that.
I would give my right arm for a high density, inexpensive switch and/or

10 Megabit is still pretty fast for a downlink from ISP-Customer.

The power supplies on the ME3400s have 2 inputs, for breaker
