  • 1.  OSPPF LSA

    Posted 29 days ago

    Hi, 

    I'm currently studdying for my JNCIP-SP certification.

    In the Juniper self training material I understood that the presence of the asterix " * " in the LSA when using "show ospf database  router|external|network|"and so on" extensive" command mean that the LSA has been originated from the router where this command command is run.

    As example in the follwing print screen according to the asterix pointed by the red arrow this LSA been orginated from R1, router on which the command "show ofps database router extensive" been run.

    From Juniper On demand course "Advanced Junos Service Provider routing : OSP" Link-State Advertisements : Part2 page: 3 of 12  

    It also what it said in the audio, that's fine.

    But later in the same coure, but in section Link-State Advertisements : Part 3, page 3 of 12

    This time the asterix is missing, but in the audio it's again said that LSA has been originated from R1....  :) is it a mistake in the course material or I missed understood something  ?

    Thank you

    The LSA in the last output is from the "View of R1".  However the originating router (Adv Rtr) is 192.168.40.1 which is R5.
