Why does the command "spanning-tree mst simulate pvst disable" exist

That's all really. Why would you turn it off? What is the advantage. If you're not receiving PVST BPDUs, you don't need it, but why turn it off?

When you use the spanning

When you use the spanning-tree mst simulate pvst disable command, specified MST interfaces that receive a Rapid PVST+ (SSTP) bridge protocol data unit (BPDU) move into the STP blocking state. Those interfaces remain in the inconsistent state until the port stops receiving Rapid PVST+ BPDUs, and then the port resumes the normal STP transition process.

 

OK, that's what it does, but why? the only effect it has is blocking your ports.
