  1. Hi Rene,

    Good lesson. Just two points in your text:

    “This is what makes EIGRP a FAST routing table…”
    Shouldn’t be a fast routing protocol?

    “Next step is to fill in the feasible successors”
    I believe here that you wanted to say feasible distances

    Thanks,

  2. Hi Rene,

    This is all I have to say, THANK YOU! :clap::clap::clap:

    Complicated concepts, made very objective.

  3. Hello Ziad

    R3 will share its own advertised distance to the destiation with R4 and not the advertised distance reported by R1 and R2. So R3 will share an AD of 9 to the destination with R4.

    In general, in EIGRP a router will share its own AD with other routers and the the AD reported by other routers.

    I hope this has been helpful!

  4. Hi Ziad,

    In reality, when R3 receives an update from R1 or R2 about the destination behind R4, it won’t install them since these don’t pass the feasibility condition (AD of the feasible successor has to be lower than FD of successor).

    R3 will only advertise its successor route to other neighbors. In this topology, R4 is the successor route so normally R3 would advertise this route to R4. However, because of split horizon (don’t advertise a route to a neighbor if you learned that route from the neighbor)…this route is not advertised.

    It might be helpful to see a

  5. The topology is being viewed from the standpoint of R3. We have the benefit here of seeing the full network topology, and you can trace if R3 used R1 or R2 as a feasible successor, to reach the destination, you’ll be going in a loop back to R3 (where you started).
