  • @johnmacward thanx

  • @MrAnsh1991 Nope, this is done pretty in depth in CCNA. In CCNP I here it's an entire book!

  • Better than the Netacad webite !

    

  • Extremely easy to follow. Thanks

  • @akimali

    Why is that? How can you decide that S1 has to be the root bridge or S3 cannot be the root bridge. To decide the root bridge in a network with the default switch values which are the same brand you need the MAC addresses of the switches. According to the video no one can decide the root bridge. What you are watching in the video is just an example. Only one of the probabilities is simulated there.

  • I really like this video but I have one question/comment. All things being equal in your diagram, when STP gets implemented, won't the packet at 3:18 get dropped at switch S3's outgoing interface instead of at switch S1's incoming interface? With all values defaulted, switch S1 will be the root bridge which will put all its interfaces in a forwarding state correct?

  • wow!

  • is this is for ccnp silabus

  • Great video. Easy to understand. You're a legend.

  • Thank you!
