OcNOS SP : Segment Routing Guide : Segment Routing Configuration : ISIS Segment Routing Micro-Loop Avoidance
ISIS Segment Routing Micro-Loop Avoidance
Micro-loop avoidance provides a mechanism leveraging SR to ensure loop-freeness during the IGP re-convergence process following a link-state change event. Using segment routing, a headend can enforce an explicit path without creating any state along the post-convergence path. As a result, a converging node can enforce traffic on the post-convergence path in a loop-free manner, using a SID list (typically short). So nodes converge over their new optimal path, but temporarily use an SR policy to ensure loop-freeness over that path.

In the forwarding tables above, the configured prefix SIDs are in the Out-Label column which is expected and is global across the topology. The swap happens in between nodes with this prefix SID and there is no local labelling.
Also verify the ILM and FTN tables.
