  1. Hi Rene

    Got a couple of questions - firstly after a while you stopped using the acronym LFA and used LSA instead - are they in fact the same thing? (I keep thinking of the completely unrelated Link State Advertisment when I read that!)

    “When you have multiple possible LSAs, fast reroute has to select one LSA. EIGRP will not just select the “best” (lowest metric) feasible successor but uses some “tie-breakers” to select the best LSA. When you use per-prefix LSA, we have these four attributes:”

    Also, is the tiebreaker “Lowest repair path metric” effectively just the normal EIGRP way of selecting the best path via lowest metric? (but actually installing it in the routing table)

    Thanks

  2. Hi @chrisnewnham17

    Sorry for the confusion, it should be LFA not LSA :smile: Just fixed this.

    Lowest repair path metric basically means that EIGRP selects the feasible successor with the lowest metric as the LFA. All other feasible successors are ignored.
