MPLS Optical User Network Interface Commands on Cisco IOS XR Software
This chapter describes the commands used to configure, monitor, and troubleshoot an Optical User Network Interface (O-UNI). It provides a description of the Static Link Management Protocol (LMP) commands. LMP is a user-configured version of the Internet Engineering Task Force's (IETF) LMP; hence, the keyword lmp is used in the management commands.
The Unified Control Plane (UCP) (sometimes referred to as the Optical Control Plane [OCP]) is a standards-based approach toward an open architecture for the control and provisioning of optical transport elements and capacity. It allows customers to establish standards-based Optical Internetworking Forum (OIF) connections through heterogeneous optical networks (OTNs) based on the Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) specifications. These connections are made across OTNs comprising Cisco equipment or third-party vendor equipment.
For detailed information about MPLS concepts, configuration tasks, and examples, refer to the
Cisco IOS XR MPLS Configuration Guide.
destination address ipv4
To establish an O-UNI connection to a specific destination transport network address (TNA), use the destination address ipv4 command in MPLS O-UNI interface mode. To return to the default behavior, use the no form of this command.
destination address ipv4 destination-TNA
no destination address ipv4 destination-TNA
Syntax Description
destination-TNA |
Destination TNA to which a connection is created. |
Defaults
No default behavior or values

Usage Guidelines
To use this command, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.
Use the destination address ipv4 command whenever an O-UNI connection is established by the router. Both O-UNI-C sides participating in an O-UNI connection is configured with the destination address ipv4 command. In this case, the destination TNA specified by each side must correspond to the TNA configured by the other side.
Note Based on the contention detection and backoff mechanisms defined in O-UNI 1.0, one of the routers acts as though configured with the passive command.
Examples
The following example shows how to configure the interface to initiate an O-UNI connection to TNA 10.10.10.10:
RP/0/RP0/CPU0:router# config
RP/0/RP0/CPU0:router(config)# mpls optical-uni
RP/0/RP0/CPU0:router(config-mpls-ouni)# interface POS 0/1/0/1
RP/0/RP0/CPU0:router(config-mpls-ouni-if)# destination address ipv4 10.10.10.10
Related Commands
ipcc routed
To configure an Internet Protocol Control Channel (IPCC) that is routable, use the ipcc routed command in O-UNI LMP neighbor configuration mode. To return to the default behavior, use the no form of this command.

Usage Guidelines
To use this command, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.
This type of IPCC is IPv4 routed to the O-UNI neighbor to which it is connected. Ensure that the O-UNI neighbor is configured with a reachable IPv4 node ID.
When a routed IPCC is configured to a given neighbor, control traffic destined to that neighbor is IP routed to the configured remote router ID for that neighbor. A correctly configured routed IPCC to a given LMP neighbor is required before an O-UNI label switched path (LSP) connection to that neighbor is established.
Examples
The following example shows how to configure a routed IPCC for O-UNI neighbor router1 where the destination IP address is the node ID of the neighbor router1 on an interface determined dynamically by an IP routing protocol:
RP/0/RP0/CPU0:router# config
RP/0/RP0/CPU0:router(config)# mpls optical-uni
RP/0/RP0/CPU0:router(config-mpls-ouni)# lmp neighbor router1
RP/0/RP0/CPU0:router(config-ouni-nbr-router1)# ipcc routed
lmp neighbor
To configure or update a new or existing O-UNI specific LMP neighbor and its associated parameters, use the lmp neighbor command in MPLS O-UNI configuration mode. To return to the default behavior, use the no form of this command.
lmp neighbor neighbor-name
no lmp neighbor neighbor-name
Syntax Description
neighbor-name |
Text string representing the name of the LMP neighbor. |

Neighbor names must be unique. A neighbor does not become operational until both the remote node ID and a routed Internet Protocol Control Channel (IPCC) are configured for that neighbor.
Note You can configure up to ten LMP neighbors for each router.
Examples
The following example shows how to enter LMP neighbor configuration mode for neighbor router 1, and create the LMP neighbor if it does not already exist.
RP/0/RP0/CPU0:router# config
RP/0/RP0/CPU0:router(config)# mpls optical-uni
RP/0/RP0/CPU0:router(config-mpls-ouni)# lmp neighbor router 1

If you need assistance with your task group assignment, contact your system administrator. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of Cisco IOS XR System Security Configuration Guide.
Use the passive command whenever the router is to terminate an O-UNI connection. The interface accepts the incoming connection request of any O-UNI-C. The router does not actively attempt to create a connection, but rather waits for an incoming connection request.
Note If a destination address ipv4 command is configured, you must enter the no destination address ipv4 command before attempting to configure the passive command. Otherwise, you receive an error.
Examples
The following example shows how to configure PoS interface 0/1/0/1 as the passive end of an O-UNI:
RP/0/RP0/CPU0:router# config
RP/0/RP0/CPU0:router(config)# mpls optical-uni
RP/0/RP0/CPU0:router(config-mpls-ouni)# interface POS 0/1/0/1
