Your network contains a server named Server1. Server1 runs Windows Server 2008 R2 and has a single network connection. The connection is configured to use a default gateway address of 10.0.0.1. The default gateway has a metric value of 100. You configure a second default gateway that uses an address of 10.0.0.2. You need to ensure that 10.0.0.2 is only used as the default gateway if 10.0.0.1 is unreachable.
