Avoid microloops in IS-IS-SRv6 networks

You can enable post-convergence path calculation on a device to avoid microloops if a link or metric changes in an SRv6 network. Note that microloop avoidance is not a replacement for local repair mechanisms such as topology-independent loop-free alternate (TILFA), which detects local failure very fast and activates a precomputed loop-free alternative path. To configure microloop avoidance in an SRv6 network, include the microloop avoidance postconvergence- path delay milliseconds statement at the [edit protocols isis spf-options] hierarchY level.
