I think it would be related to how the NSIS state for the tunneling part is
managed. I.e., which flow ID/session ID would be used for this section.

As the triangular route is backup route of the optimized route, the
tunneling path might need to be kept with reduced resources (though keeping
backup path will cause signaling overhead).
