IP Router Configuration
Router Configuration Guide 165
Default No interfaces or names are defined within the system.
Parameters ip-int-name — The name of the IP interface. Interface names must be unique within the 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. If the string contains special
characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.
Values 1 to 32 alphanumeric characters.
If the ip-int-name already exists, the context is 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 the context will not be
changed to that IP interface. If ip-int-name does not exist, the
interface is created and the context is changed to that interface for
further command processing.
unnumbered-mpls-tp — Specifies that an interface is of type Unnumbered MPLS-TP. An
unnumbered MPLS-TP interface is a special type of interface that is only intended for MPLS-
TP LSPs. IP routing protocols are blocked on interfaces of this type. If an interface is
configured as unnumbered-mpls-tp, then it can only be associated with an Ethernet port or
VLAN, using the port command. Either a unicast, multicast or broadcast remote MAC
address may be configured using the static-arp command. Only static ARP is supported.
gmpls-loopback — Specifies that the interface is a loopback interface for GMPLS control plane
packets.

no address
Context config>router>interface
Description This command assigns an IP address, IP subnet, and broadcast address format to an IP interface. Only
one IP address can be associated with an IP interface.
An IP address must be assigned to each IP interface. An IP address and a mask combine 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 router.
The local subnet that the address command defines must not be part of the services address space
within the routing context by use of the config router service-prefix command. Once a portion of the
address space is allocated as a service prefix, that portion is not available to IP interfaces for network
core connectivity.
The IP address for the interface can be entered in either CIDR (Classless Inter-Domain Routing) or
traditional dotted decimal notation. Show commands display CIDR notation and are stored in
configuration files.
