  1. Hi Rene,


    My question is :-

  2. i didn’t understand this
    and i show command its show me share count

    Router#show ip route
    Routing entry for
      Redistributing via eigrp 1
          Route metric is 156416, traffic share count is 240
          Total delay is 5110 microseconds, minimum bandwidth is 100000 Kbit
          Reliability 255/255, minimum MTU 1500 bytes
          Loading 1/255, Hops 2
      *, from, 00:01:11 ago, via Serial5/0
          Route metric is 640256, traffic share count is 59
          Total delay is 5010 microseconds, minimum bandwidth is 5000 Kbit
          Reliability 255/255, minimum MTU 1500 bytes

    Hi Hussein,

    It will be shared in proportion based on the feasible distance. If the successor had a FD of 100 and the feasible successors had a FD of 20 and 10 then you’d see a 10:2:1 ratio.



  3. Hello Florain


    If you do unequal cost LB, then the routes in the routing table are also considered successors and not feasable successors. But putting aside terminology, the answer is yes, the routes that were FS (at least the next one(s) in line) is inserted into the routing table and becomes a successor.

    The deciding factor of choosing the next successor is always the same, regardless of whether or not you are using load balancing. EIGRP will keep up to six feasible successors in the topology table and only the one (or ones) with the best metric (or metrics) become the successor(s) and are placed in the routing table.

    I hope this has been helpful!


  4. Hello Marcel


    So, the routing table will only have a single route to a particular destination by default (unless two routes have an equal metric of course). In order to determine if a route can be used for unequal load balancing, the variance value is used and the calculation as described above is implemented on the metrics found in all routes within the topology table. If the metric of the route fulfills the metric * variance > FD condition, then it is then installed in the routing table as well, as a secondary, unequally load balanced route.

    So the topology table is used in this whole evaluation of routes because it is there that all the available routes and their metrics are found.

    I hope this has been helpful!
