Shim6 has not suceeded, but misunderstanding the need for timeouts and probes was not the reason. There is some further discussion of this issue, with experimental and simulation results, in https://tools.ietf.org/html/draft-naderi-ipv6-probing-01 . I have never found it very helpful to accuse discussion partners of stupidity. Regards Brian
