[j-nsp] thoughs on MVRP?

[Luca Salvatore]

I don't really need to run STP on them, these are switchports connecting into physical servers which host hundreds of VMs, so I need to trunk all my vlans into about 20 ports per switch

Not quite sure how Q-in-Q would help... How do I configure the ports facing the servers, who does the tagging?

MVRP looks more like cisco's VTP, so probably not what i'm after right?

If you don't need to run STP on these VLANs, why not use
QinQ/dot1q-tunneling?
