Avoid microloops in OSPFv2 segment routing networks

You can enable post-convergence path calculation on a device to avoid microloops if a link or metric changes in an OSPFv2 segment routing network. Note that microloop avoidance is not a replacement for local repair mechanisms such as topology-independent loop-free alternate (TI-LFA), which detects local failure very fast and activates a precomputed loop-free alternative path. To configure microloop avoidance in an OSPFv2 segment routing network, include the maximum-labels and delay milliseconds statements at the [edit protocols ospf spf-options microloop avoidance post-convergence-path] hierarchy level.
