That seems to assume that a failure will produce a map change.
I expect a failure to produce a change in the routing tables,
but why should a (temporary) failure produce any change
in the map? I would expect this would cause the routing
algorithm to be told about the failure and to find an alternative
path involving the same or an alternative map entry.
