I looked over the CCIE R&S exam topics and noticed some knobs and tools that are used for OSPF. Such as LFA and OSPF FRR, are these tools used in the real world often? Does throttling make a difference these days with the router hardware we have today?
My understanding of OSPF FRR
There are backup paths for a given prefix already precomputed. Resulting in faster convergence. (Obivous).
There is per-prefix and per-path
Per-Prefix has more entries which results in more memory use but is better on failover.
Per-Path has less entries since all prefixes will get associated with a single path, but can be harder on alternate paths during failover.
