I think you are asking about the definition of "invalid", which is specified in RFC 4862. (It is when the address allocation is withdrawn, whether using stateless address allocation or DHCPv6.) In an implementation that typically corresponds to the address no longer being configured e.g., doesn't show up in ifconfig -a. This is completely unrelated to an address being unreachable. Note that the address allocation needs to be withdrawn before the address can possibly be reassigned to some other node. > When that locator _does_ respond, but with invalid context (or some > other expected 'error' behavior)? > When it becomes un-routable? (prefix change) I don't know what an "invalid context" means. Please explain. A shim6 host can loose state, which can result in one end having context state and the other end not having it. RFC 5533 specifies how the protocol recovers from context state loss. Erik
