MSTP Sample Configurations
The running-configurations in Figure 30-132, Figure 30-133, and Figure 30-133 support the topology
shown in Figure 30-131. The configurations are from FTOS systems. An S50 system using SFTOS,
configured as shown Figure 30-135, could be substituted for an FTOS router in this sample following
topology and MSTP would function as designed.
