Explains how SRv6 microloop avoidance maintains stable packet forwarding during IS-IS convergence and provides the guidance needed to configure temporary loop-free paths.
SRv6 microloop avoidance is a SRv6 feature designed to prevent brief, transient packet loops that occur during network topology changes. These microloops can cause packet loss and jitter, but this feature detects such possibilities and temporarily steers traffic onto loop-free paths, ensuring stable forwarding during network convergence. This significantly enhances network stability, performance, and the overall user experience.
SRv6 microloop avoidance
Explains how temporary SR-TE paths prevent transient forwarding loops, packet loss, jitter, and out-of-order delivery while the network converges after a topology change.
Limitations of SRv6 microloop avoidance
Identifies the supported range and default value of the RIB update delay that determines how long temporary microloop-avoidance paths remain active.
How SRv6 microloop avoidance works
Describes how routers detect possible microloops, install temporary SID-list paths, wait for network convergence, and transition traffic to native post-convergence forwarding.
Configure SRv6 IS-IS microloop avoidance
Provides instructions for enabling SRv6 microloop avoidance under IS-IS and configuring the RIB update delay used for temporary loop-free forwarding.
