Bridge Root refers to the base of the spanning tree (the root bridge). Our Bridge is this
Switch. This Switch may also be the root bridge.

address. This ID is the same for Root and Our Bridge if the Switch is the root
switch.
Hello Time

This is the time interval (in seconds) at which the root switch transmits a
configuration message. The root bridge determines Hello Time , Max Age and
Forwarding Delay

configuration message before attempting to reconfigure.
Forwarding Delay
(second)
This is the time (in seconds) the root switch will wait before changing states (that
is, listening to learning to forwarding).
Cost to Bridge This is the path cost from the root port on this Switch to the root switch.
Port ID This is the priority and number of the port on the Switch through which this switch
must communicate with the root of the Spanning Tree.
