OSPF Loop-Free Alternate (LFA) Fast Reroute (FRR) allows OSPF to quickly switch (within 50 ms) to a backup path when a primary path fails.

When OSPF has to select a backup path, it doesn't just look for the“next best”

Loop Free Alternate (LFA) is a mechanism by which neighbours can be used as backup hops

OSPF Loop-Free Alternate  Fast Reroute allows OSPF to quickly switch (within 50 ms) to a backup path when a primary path fails. Without LFA FRR, OSPF has to re-run SPF to find a new path when the primary path fails.

Per prefix LFA is a mechanism by which LFA to a non-best prefix originator can be used in lieu of the LFA to the best prefix originator to provide local repair. In such cases, per prefix LFA can be used to increase the local repair coverage for the OSPF protocol.
