Description
This command creates a logical IP routing interface for an Internet Ethernet Service (IES). Once
created, attributes like an IP address and service access point (SAP) can be associated with the IP
interface.
The interface command, under the context of services, is used to create and maintain IP routing
interfaces within IES service IDs. The interface command can be executed in the context of an IES
service ID. The IP interface created is associated with the service core network routing instance and
default routing table. The typical use for IP interfaces created in this manner is for subscriber internet
access. An IP address cannot be assigned to an IES interface. Multiple SAPs can be assigned to a
single group interface.
Interface names are case sensitive and must be unique within the group of defined IP interfaces
defined for config router interface and config service ies interface (that is, the network core router
instance). Interface names must not be in the dotted decimal notation of an IP address. For example,
the name "1.1.1.1" is not allowed, but "int-1.1.1.1" is allowed. Show commands for router interfaces
use either interface names or the IP addresses. Use unique IP address values and IP address names to
maintain clarity. It could be unclear to the user if the same IP address and IP address name values are
used. Although not recommended, duplicate interface names can exist in different router instances.
The available IP address space for local subnets and routes is controlled with the config router
service-prefix command. The service-prefix command administers the allowed subnets that can be
defined on IES IP interfaces. It also controls the prefixes that may be learned or statically defined
with the IES IP interface as the egress interface. This allows segmenting the IP address space into
config router and config service domains.
When a new name is entered, a new logical router interface is created. When an existing interface
name is entered, the user enters the router interface context for editing and configuration.
By default, there are no default IP interface names defined within the system. All IES IP interfaces
must be explicitly defined. Interfaces are created in an enabled state.
The no form of this command removes IP the interface and all the associated configuration. The
interface must be administratively shutdown before issuing the no interface command.
For IES services, the IP interface must be shutdown before the SAP on that interface may be
removed. IES services do not have the shutdown command in the SAP CLI context. IES service
SAPs rely on the interface status to enable and disable them.
Parameters
ip-int-name — Specifies the name of the IP interface. Interface names must be unique within the
Page 728
group of defined IP interfaces for config router interface and config service ies interface
commands. An interface name cannot be in the form of an IP address. Interface names can be
from 1 to 32 alphanumeric characters. If the string contains special characters (#, $, spaces, etc.),
the entire string must be enclosed within double quotes.
