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?

Bridge Identifier has priority 128, address 0007.50c1.0700
Configured hello time 2, max age 20, forward delay 15
Current root has priority 128, address 0006.5b4b.e1da
Root port is 3 (Ethernet0/1), cost of root path is 200
Port Number size is 9
Topology change flag not set, detected flag not set
Times: hold 1, topology change 35, notification 2
hello 2, max age 20, forward delay 15
Timers: hello 0, topology change 0, notification 0
