We use MC-LAG between Extreme and Foundry gear, and it works just fine.
I had no doubt companies had their own proprietary implementations of SMLT-like features. I was just saying it was a shame that there still isn't a standard for SMLT/MC-LAG more than a decade after the first proprietary implementations on Ethernet gear.
Then again, I suppose a standard is not absolutely required since router/switch manufacturers can achieve almost the same result by bending the LACP/LAG rules a little to allow proxying.
