To add info from my end, I belive the CCR 1036 is massively overpowered, but I 
will conduct some tests on my own ;)
I expect the CCR1036 can saturate 4-8x Gbit that way.

Betreff: Re: [swinog] Transparent 1Gig Ethernet over IP/Ethernet?

Unfortunately, QinQ (which is called "vman" in the Extreme Networks world) does 
not work with LACP. Corroborating to the problem is the fact that the LAG ports 
originate on the same switch that provides the transport vmans. Since QinQ 
transports share src/dst MAC address-space with the connected "customer" VLANs, 
the "direct" approach does not even work for non-LACP LAGs. 

I successfully employed encapsulation of the LACP LAG legs with a pair of 
EdgeMAX Lite routers, configured for L2 GRE Bridging. I was then able to pipe 
the encapsulated LAG legs back into the Summit X460 Switch where they 
originally came from, and transport them over the vmans. Unfortunately, the 
performance achieved by this solution (~350mbps on a single leg) is far from 
sufficient. 

Two kind members of the NANOG mailing list pointed me to ethernet demarcation 
devices (E-Line being of interest here) from accedian and ciena, which might 
just do the trick at GigE wire speed: 

http://www.accedian.com/en/products/ethernid-family.html 
http://www.ciena.com/products/3902/ 

Silvan also pointed out that Mikrotik's EoIP might provide adequate performance 
when provided by a pair of CCR1036 36 core CPU routers. However, it looks as if 
the accedian/ciena devices would offer a much more cost-effective approach.
