About the DT4 and DT6 tests, I thought to use the same method as the failure was practically the same as End.DT46. This is the version I'm currently using ip utility, iproute2-ss200127 (should be 5.5.0 if I'm not mistaken) and I can confirm [SEG6_LOCAL_ACTION_END_DT4] = "End.DT4" [SEG6_LOCAL_ACTION_END_DT6] = "End.DT6", is available. What do you suggest would be the right way forward to check what is going on? Kind regards, -Alessio Faina
