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-forwarding-14 is proposing a mechanism which will
divert the traffic based on nodes being upgraded to support the protection. The paths
could be quite divergent from post-convergence path and an operator would be expected
to do planning to ensure these paths have sufficient bandwidth to take on traffic.
