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.
By default, no IP address or subnet association exists on an IP interface until it is explicitly created.
The no form of the command removes the IP address assignment from the IP interface. Interface
specificconfigurations for MPLS/RSVP are also removed. This will operationally stop any MPLS
LSPs that explicitly reference that IP address. When a new IP address is defined, interface specific
configurations for MPLS/RSVP will need to be re-added. If the no form of the command is executed
then ptp-hw-assist is disabled. If a new address is entered while another address is still active, the
new address will be rejected.
Default No IP address is assigned to the IP interface.

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 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.
