OSPF – Loop Free Alternate Fast Reroute
Introduction The OSPF Loop-Free Alternate Fast reroute feature can be implemented to optimize convergence within an OSPF routing-domain. It reuses an already precomputed alternate path (next-hop) to reduce the reaction time in case that the primary path fails. It gives you the option to precompute a per-prefix loop-free alternate (LFA) path which redirects the traffic […]
