Isn’t the point about TI-LFA that it re-routes on the post convergence path to avoid micro-loops. When you overestimate the failure to provide node protection even though the failure was not a node failure, the repair path may not be congruent with the post convergence path in which case you n

WG, Regarding Peter's comment on the mic that TI-LFA can divert from post convergence path when SRLG is used for computation I would like to clarify that an operator is expected to do planning for the post convergence path accounting for the SRLG failures. draft-hu-spring-segment-routing-proxy-
