IOS-XR MPLS TE Auto Tunnel Backup Bandwidth Protection

WebFRR is a mechanism to protect against RSVP-TE signaled LSP failures by reacting to these failures as soon as possible. FRR is set up from the ILER, which signals the transit routers to precompute their backup LSPs. FRR creates a precomputed backup LSP from each node in the LSP path. WebFeb 16, 2015 · Per-Link: Per link LFA just looks at the primary link and based on inequality condition#1 it determines if there is a backup path to that link.
