MSTP Sample Configurations
The running-configurations in Figure 30-11, Figure 30-12, and Figure 30-12 support the topology shown
in Figure 30-10. The configurations are from FTOS systems. An S50 system using SFTOS, configured as
shown Figure 30-14, could be substituted for an FTOS router in this sample following topology and MSTP
would function as designed.
