Describes IP fast reroute loop-free alternate for Cisco 8000 Series Routers running IOS XR. Use this topic to understand the OSPF behavior, dependencies, and design considerations before you configure or verify the feature.
IP fast reroute loop-free alternate is a concept that explains OSPF behavior, dependencies, and operational context for Cisco 8000 Series Routers.
This task describes how to enable the IP fast reroute (IPFRR) per-link loop-free alternate (LFA) computation to converge traffic flows around link failures.
This task describes how to enable the IP fast reroute per-link loop-free alternate computation so that traffic can converge around link failures.
To enable protection on broadcast links, IP fast reroute and Bidirectional Forwarding Detection (BFD) must be enabled on the interface under OSPF.
