Description This command assigns an IP address, IP subnet, and broadcast address format to an IES IP router 
interface. Only one IP address can be associated with an IP interface.
An IP address must be assigned to each IES IP interface. An IP address and a mask are used together 
to create a local IP prefix. The defined IP prefix must be unique within the context of the routing 
instance. It cannot overlap with other existing IP prefixes defined as local subnets on other IP 
interfaces in the same routing context within the 7750 SR.
