Configuring IP Addressing
A required task for configuring IP routing is to assign IP addresses to Layer 3 network interfaces to
enable the interfaces and allow communication with the hosts on those interfaces that use IP. These
sections describe how to configure various IP addressing features. Assigning IP add re sses to the
interface is required; the other procedures are optional.
