In STP, a non-root-bridge switch can have two root ports


True

False

 

##########################################


    First, to answer this question, we need to remember how is performed the root bridge election and port role selection.


    All bridges on an STP network have a bridge ID composed of two parts.


1


    When STP starts to work, all bridges send to your neighbors your configuration BPDU and the smallest bridge ID is elected as Root Bridge.


2



    An STP network has only one Root Bridge, and all other equipment is called non-root.

    After this election, we need to choose the port roles to prevent loops on the network. All ports will receive one of these roles:

-          Designate Port

-          Root Port

-          Alternate Port

    By mastering this process, we can easily answer the question.

    A Root Bridge sends your configuration BPDU through all ports. The ports of a Root Bridge receive the role of Designate Port.

    The Non-root bridges select the port from where receive the configuration BPDU as the Root Port.

    If the Non-root bridge receives Configuration BPDU through more than one port, it promotes the election of the best path, and the port of this path is selected as Root Port.


3



    With this process on our mind, we see that each non-root bridge has only one root port because the main function of the STP protocol is to ensure that there are no active redundant paths.

 

    The correct answer is FALSE.
