Bridge A broadcasts a packet to Bridge C, then Bridge C will drop
the packet at port 2 and the broadcast will end there.
Setting-up STP using values other than the defaults, can be
complex. Therefore, you are advised to keep the default factory
settings and STP will automatically assign root bridges/ports and
block loop connections. Influencing STP to choose a particular
switch as the root bridge using the Prioritysetting, or influencing
STP to choose a particular port to block using the Port Priority
and Port Costsettings is, however, relatively straight forward.

In this example, only the default STP values are used.
