Identify the bridges that transmit BPDUs after the spanning tree protocol has converged. For each Ethernet segment, determine the following fields for the BPDU sent on that segment: root ID, root path cost, and bridge ID. Explain how these message are interpreted. Show how the entire spanning tree can be constructed from these messages.

What will be an ideal response?
