It means a forwarding node that uses the exception added by RFC7045 and simply doesn't even look for an HbH header. The flag bits are invisible and irrelevant to such a node. The flag bits apply as defined for a forwarding node that *does* process HbH options, so they certainly should not be deprecated. Brian > > In that case, the flags have exactly no meaning anywhere.
