I agree that using the "preferred lifetime" for signaling that a

to zero) to inform the hosts that a prefix is no longer available?
If you have non-shim6 hosts, then a valid lifetime set to zero might
mean that they'll immediately terminate any tcp connections that use
that prefix. I don't think we want to do that, because packets might
start flowing again before e.g., TCP gives up.
So I think that if we are going to add an indication that a prefix
isn't working, so that shim6 hosts can change the locator they use
more quickly,
