Hello,
I'm looking for a solution to realise loop protection in MLAG design with non exos edge-switches.
- a dedicated STP-domain per edge-switch is a option when only 1 switch is in a location.
- How can I realise a comprehensive loop-protection between 2 edge-switches in a location, which are both connected via MLAG?
I've 2 use-cases...
- edge-switches are HP Procurve
- edge-switches are EOS Devices
Can somebody give me a bit input?

I'd use STP on each edge switch's edge ports (so not facing back towards the MLAG peers), with edge-safeguard and BPDU-restrict or whatever the equivalent is on your edge switches.
The key is that we want the edge switches to transmit BPDUs out the edge ports and block whenever they receive a BPDU on an edge port. This way, if Edge2 gets looped in to Edge3, they will see each other's BPDUs and block the ports.

Hmmm... not sure how exactly all involved switches are connected with each other.
Can you maybe add a network diagram here, should the connections between the involved switches and where you have configured LAGs and MLAG?
