Spanning Tree Cost Calculation Page Question

Routing & Switching Spanning Tree
1

Hello,

Looking at the Spanning Tree Cost Calculation Page, it says:

SW3 will forward BPDUs to SW4. The root path cost field will be 100.
SW4 receives a BPDU from SW2 with a root path cost of 19.
SW4 receives a BPDU from SW3 with a root path cost of 100.

Shouldn’t the root path cost from Sw3 to Sw4 be “4” since its a 1000 mbps link?

Thanks for any clarification to assist my understanding.

Chris
