    if we have a switch port configured to have a seitchport security with maximun 1 mac address, and i was connected to another switch, and the other switch already connected with many PCs, so how the proccess is going to be with the secured port, is it going to consider all that PCs as on mac address because its connected to on mac address which is the second switsch mac address, or it is going to deal with each PC as unique mac address ? thank you

    Hey guys, correction here - K values are actually stored as 8 bit value, so we can have 256 values (0-255], not 128.

    Why the reported distance received for that router must be less than the feasible distance calculated locally to guarantees a loop-free path??

    • @jastorino
      @jastorino 3 года назад

      Hey David - Basically, when the AD/RD reported is < the FD, the router receiving the route is able to say “OK, the router advertising this prefix is closer to the destination than I have ever been”, and that is good enough. There could be paths that are actually both loop free and do not meet the FC, but the algorithm is a bit conservative.
