Describes how SPF scheduling, prefix prioritization, topology controls, route summarization, resource-protection mechanisms, and loop-free alternates improve OSPF scalability, convergence, and traffic protection during topology changes and link failures.
OSPF scale, optimization, and protection features
Describes OSPF scaling, optimization, and protection features for Cisco 8000 Series Routers running IOS XR, including OSPF behavior, dependencies, and key design considerations.
Configure OSPF SPF scheduling and prefix prioritization
Configure OSPF SPF scheduling and prefix prioritization to optimize route convergence.
Configure OSPF scale and topology controls
Set up multiple OSPF areas on a primary interface and summarize routes to reduce LSA count and optimize network resource usage.
IP fast reroute loop-free alternate
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.
