4.5.8.2 Provisioning Parameters
Many of the commands and parameters for MSTP are similar to (R)STP, since the user is still creating an (R)STP
instance that must go through a convergence process. However, some parameters are unique for MSTP, or
some value for a common parameter is different, and these are highlighted.
Following are the key parameters that are data filled for (R)STP; for each there is a summary for the parameter
(or a reference to an earlier subsection, especially 4.5.3.6), and how MSTP uses the parameter.
