WebJun 7, 2024 · This document describes how Loop-Free Alternate (LFA) mechanism provides fast reroute of traffic in network. It also discusses two types of LFA protection- Link protection and Node protection and their applicability in order to provide minimum disruption to services because of a link or node failure. Prerequisites Requirements WebPreliminary numerical evaluations conducted on real IP network topologies suggest that rLFA significantly improves the level of protection, and most networks need only 2 - 3 new links to be added to attain 100% failure case coverage. Up to not so long ago, Loop-Free Alternates (LFA) was the only viable option for providing fast protection in pure IP and …

WebFast Reroute Overview. Fast reroute provides redundancy for an LSP path. When you enable fast reroute, detours are precomputed and preestablished along the LSP. In case of a network failure on the current LSP path, traffic is quickly routed to one of the detours. Figure 1 illustrates an LSP from Router A to Router F, showing the established ...
