RPR Path Analysis
To perform a path analysis, select Network > Path & Capacity > Path... Then click a source router attached to an SRP interface and a destination router attached to an SRP interface. Note that the resulting demand will be on the shortest path.

Try failing the link connecting pseudo-nodes RTRC_SRP1/0 and RPRB_SRP1/0. Now a path analysis reveals that the path now wraps around the other side of the ring.
