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.
In the IES subscriber interface context, this command is used to assign one or more (16 maximum)
host IP addresses and subnets. This differs from a normal IES interfaces where the secondary
command creates an additional subnet after the primary address is assigned. A user can then add or
remove addresses without having to keep a primary address.
The local subnet that the address command defines must be part of the services address space within
the routing context using the config router service-prefix command. The default is to disallow the
complete address space to services. Once a portion of the address space is allocated as a service
prefix, that portion can be made unavailable for IP interfaces defined within the config router
interface CLI context for network core connectivity with the exclude option in the config router
service-prefix command.
The IP address for the interface can be entered in either CIDR (Classless Inter-Domain Routing) or
traditional dotted decimal notation. The show commands display CIDR notation and is stored in
configuration files.
By default, no IP address or subnet association exists on an IP interface until it is explicitly created.
Use the no form of this command to remove the IP address assignment from the IP interface. When
the no address command is entered, the interface becomes operationally down.

If ip-int-name already exists within the service ID, the context will be changed to maintain that
IP interface. If ip-int-name already exists within another service ID or is an IP interface defined
within the config router commands, an error will occur and context will not be changed to that
IP interface. If ip-int-name does not exist, the interface is created and context is changed to that
interface for further command processing.
