I am not sure fe80::1 as a default route is standardized in an RFC, so to say? I can agree though it is often used in practice. > There is nothing for an adversary to be gained here.

Just that some times one can get on-link because one legitimately has the credentials, yet one does not know the default route, because it does not come from an RA but from a link-layer message exchange which might be difficult (impossible some times) to capture. I am not saying it is good or bad, just I detail the perspective, for the sake of discussion. Alex > > Gert Doering > -- NetMaster
