8.3.5.1 Path-cost Method
After deciding a root switch, you need to decide to which route you will forward the packet.
To do this, the standard is a path-cost.
Generally, a path cost depends on the transmission speed of LAN interface in the switch.
The following table shows the path cost according to the transmit rate of LAN interface.
You can use same commands to configure STP and RSTP, but their path-costs are to-
tally different. Please be careful not to make mistake.
