CCNA 2.7 Configure, verify and troubleshoot STP related optional features


The optional features of the Spanning Tree Protocol (STP) enhance loop prevention, protect against some possible user misconfigurations, and provide better control over the protocol parameters. Although similar functionality may be incorporated into the IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) standard, we recommend using these extensions. With the exception of PVST Simulation, all of these extensions can be used with both Rapid PVST+ and MST. PVST Simulation operates only with MST.

The following are the optional STP features.  The bold links are covered in the CCNA:
