  1. Hi Rene,

    I think that in configuration there is missing a static route to each of the peer’s loopback addresses.

  2. 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:

    router bgp 1
     bgp log-neighbor-changes
     neighbor R2_R3_R4 peer-group
     neighbor

  3. Hi Adiel,

    These two lessons might help to understand what is going on:

    BGP Neighbor Adjacency States

    Troubleshooting BGP Neighbor Adjacency

    Is your router able to reach 2.2.2.2, 3.3.3.3 or 4.4.4.4? Are R2, R3 and R4 able to reach 1.1.1.1? That’s something to check. Make sure the BGP configuration on R2, R3 and R4 is also using the loopback address as the source of the connection and that multihop is configured.

  4. Hi Zeko,

    I just added the static routes to the post, those are indeed required.

    Which exact commands did you remove? Do you still have your final config?

  5. 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!
