# Verify that the root bridge ID of Device B does not change and that the STP topology remains
stable after STP BPDUs with higher priority are sent to the Device B. (Details not shown.)
# Verify that the devices do not refresh the FIB table frequently and that no serious packet loss
occurs after a large number of TC BPDUs are sent to the devices. (Details not shown.)
# Verify that the uplink ports are not flooded after a large number of broadcasts are sent to the edge
ports on device A and Device C. (Details not shown.)
