Outlines IS-IS protection and resiliency features, including nonstop forwarding, NSR, enhancements during OOR conditions, overload bit suppression, global weighted SRLG protection, and penalty mechanisms for link anomalies, with configuration and operational guidelines for robust network stability.
IS-IS non-stop forwarding
Introduces IS-IS nonstop forwarding (NSF) support and provides instructions for configuring nonstop forwarding to ensure uninterrupted protocol operations during control plane restart.
ISIS Non-stop Routing
Explains ISIS Non-Stop Routing (NSR) functionality and guides users through configuration procedures to maintain routing continuity during process restarts.
IS-IS OOR protection mechanisms
Describes IS-IS protection enhancements specifically designed for out-of-resource (OOR) conditions, emphasizing mechanisms that strengthen protocol resiliency when resources are limited.
Overload bits in OOR conditions
Explains how overload bit suppression operates in OOR conditions, describes its role in IS-IS to maintain network stability, and outlines critical considerations before configuring or verifying IS-IS overload behavior.
Global weighted SRLG protections
Explains global weighted SRLG protection, details its impact on backup path selection and network resiliency with IS-IS, and outlines prerequisites, configuration types, and distribution methods for SRLG data.
IS-IS penalties for link delay anomalies
Explains IS-IS penalties for link delay anomalies, covering detection with SR-PM, automatic metric adjustments, advertisement and restoration processes, node reload behavior, and configuration guidance for managing IS-IS responses to link delay events.
IS-IS penalties for link loss anomalies
Explains iS-IS penalty for link loss anomaly and the technical context you need before you configure or verify IS-IS behavior.
