Yes, that is correct.

"MSTP, which uses RSTP for rapid convergence".....

Did i read somewhere that MST uses RSTP on each instance, with the
associated fast convergence?

        Rapid-PVST - Perceived as easier to configure than MST, allows
for more
        spanning-tree instances (64 is normally enough unless all of
your VLANs
        have a different topology).

        Bottom-line, I would say most people in an all Cisco environment
go
        Rapid-PVST (or PVST). In mixed-vendor, I would do MST.
