EIGRP Loop-Free Alternate (LFA) Fast Reroute (FRR)

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)
