Ahmed and all,Two points:1. From my POV your description of forwarding behavior when the link S-->F fails is incomplete: the top label in the stack may be poppoed, but it is not "forgotten", and the next exposed label is looked up by S in the context label space that is F-specific. I.e., if S has two downstream neighbors, F and G, and both links S-->F and S-->G fail, lookup of the next exposed label for packets with ToS being S label for F and S label for G will yield different results. 2. From my POV draft-hegde-spring-node-protection-for-sr-te-paths provides roughly equjvalent behavior, but it is much more clear when it comes to describibg the DP mechanisms involved. (IMHO and FWIW calling a spae by its name is greatly preferable in most cases.) My 2c
