  1. Hi,

    I have a problem in R1 he doesn’t create any neighbor relationship:

    These are the logs:

    *Jul  9 17:58:35.187: BGP: ses global 3.3.3.3 (0x655EF9CC:0) act Reset (Active open failed).
    *Jul  9 17:58:35.199: BGP: 3.3.3.3 active went from Active to Idle
    *Jul  9 17:58:35.199: BGP: nbr global 3.3.3.3 Active open failed - open timer running
    *Jul  9 17:58:35.203: BGP: nbr global 3.3.3.3 Active open failed - open timer running
    

    Example for R3 but it’s the same for R2 and R4:

  3. Hi Zeko,

    I see it now, the final configs of R2, R3, and R4 were wrong. They have to use 1.1.1.1 as the destination and source BGP from their own loopbacks. Just fixed this. Sorry for the confusion!

  4. Hello sales2161

    The courses on Networklessons are organized by either certification or topic. All the courses that are organized by topic include all of the information for that particular topic that is needed for certifications up to and including CCIE.

    If you’re studying specifically for a particular certification, it’s best to use the course of that particular certification. If you just want to learn about a particular topic in depth, then go for the topical courses.

    For this particular case, the BGP course goes beyond what is needed for CCNP. If you’re f
