14.8 OSPF Sham-link


Finally got through this, Had to watch a few video's and review doc cd to fully understand how this works.


  • I have been avoiding the whole sham-link component due to my weakness in MPLS. Happy to say Brian does a fantastic job explaining it in the new Advanced Tech class, and I labbed this up tonight with success. Feels good! 

  • In my experience there is definately an "aha" moment with sham-links.  The hardest part for me is when you have a partially constructed topology and then you need to implement one.  So you have to 1)Find out what has been done, and 2)Configure the rest... One of the vol2 labs does a good job with this, lab 6 I think.
