For your information:

I upgraded the 12.6.2.10 switches to 15.2.2.7, but MLAG to MLAG is a definitve no-go. I had to resort to RSTP.
Absolutely disappointing if you ask me - It would have been such an elegant solution offering redundancy and bandwidth.

Still I'd like to know why it doesn't work? MLAG is supposed to appear and act just like a normal LAG to the link partner. And since MLAG-LAG works fine, it really kinda annoys me that MLAG-MLAG does randomly blackhole my ethernet frames 😠

Any insight from the extremists here? (from Chris_Burri)
