"Floating" static routes provide a way for traffic to follow a backup static route when the router detects a link failure on the iterface used by the primary static route. However, it's increasingly less likely that link failures can be detected as the amount of equipment between routers goes up. Still, a floating static route as a backup is better than no backup at all! See the section called Exit Selection with "Floating" Static Default Routes in Chapter 7 for details.
