MPLS Traffic Engineering Commands on Cisco IOS XR Software
This chapter describes the commands that you will use to configure Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) and Generalized MPLS (GMPLS). In this chapter, all GMPLS-specific commands are identified with "(GMPLS)" in the command title.
Your network must support the following Cisco features before you can enable MPLS-TE:
•
MPLS
•
•
•
MPLS Label Distribution Protocol (LDP), Resource Reservation Protocol (RSVP), and Universal Control Plane (UCP) command descriptions are documented separately.
For detailed information about MPLS concepts, configuration tasks, and examples, refer to
Cisco IOS XR MPLS Configuration Guide.adjustment-threshold (MPLS-TE)
To configure the tunnel bandwidth change threshold to trigger an adjustment, use the adjustment-threshold command in MPLS-TE automatic bandwidth interface configuration mode. To disable this feature, use the no form of this command.
adjustment-threshold percentage [min minimum bandwidth]
no adjustment-threshold percentage [min minimum bandwidth]
Syntax Description
Defaults
percentage: 10
minimum bandwidth: 10 kbps
Command Modes
MPLS-TE automatic bandwidth interface configuration
Command History
Release 3.8.0
This command was introduced on the Cisco CRS-1 and Cisco XR 12000 Series Router.
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.
If you configure or modify the adjustment threshold while the automatic bandwidth is already running, the next band-aids application is impacted for that tunnel. The new adjustment threshold determines if an actual bandwidth takes place.
Examples
The following example configures the tunnel bandwidth change threshold to trigger an adjustment:
RP/0/RP0/CPU0:router# configureRP/0/RP0/CPU0:router(config)# interface tunnel-te 1RP/0/RP0/CPU0:router(config-if)# auto-bwRP/0/RP0/CPU0:router(config-if-tunte-autobw)# adjustment-threshold 20 min 500Related Commands
admin-weight
To override the Interior Gateway Protocol (IGP) administrative weight (cost) of the link, use the admin-weight command in MPLS-TE interface configuration mode. To return to the default behavior, use the no form of this command.
admin-weight weight
no admin-weight weight
Syntax Description
Defaults
weight: IGP Weight (default OSPF 1, ISIS 10)
Command Modes
MPLS-TE interface configuration
Command History
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.
To use MPLS the admin-weight command for MPLS LSP path computations, path-selection metric must be configured to TE.
Task ID
Examples
The following example shows how to override the IGP cost of the link and set the cost to 20:
RP/0/RP0/CPU0:router# configureRP/0/RP0/CPU0:router(config)# mpls traffic-engRP/0/RP0/CPU0:router(config-mpls-te)# interface POS 0/7/0/0RP/0/RP0/CPU0:router(config-mpls-te-if)# admin-weight 20Related Commands

Enters MPLS-TE configuration mode.
Specifies an MPLS-TE tunnel path-selection metric type.
affinity
To configure an affinity (the properties the tunnel requires in its links) for an MPLS-TE tunnel, use the affinity command in interface configuration mode. To return to the default behavior, use the no form of this command.
affinity {{affinity-value mask mask-value} | exclude name | exclude-all | include name | include-strict name}
no affinity {{affinity-value mask mask-value} | exclude name | exclude-all | include name | include-strict name}
Syntax Description

Command History
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.
Affinity determines the link attributes of the tunnel (that is, the attributes for which the tunnel has an affinity). The attribute mask determines which link attribute the router should check. If a bit in the mask is 0, the attribute value of a link or that bit is irrelevant. If a bit in the mask is 1, the attribute value of that link and the required affinity of the tunnel for that bit must match.
A tunnel can use a link if the tunnel affinity equals the link attributes and the tunnel affinity mask.
Any properties set to 1 in the affinity should be 1 in the mask. The affinity and mask should be set as follows:
tunnel_affinity=tunnel_affinity and tunnel_affinity_maskYou can configure up to 16 affinity constraints under a given tunnel. The following constraints are used to configure affinity constraints for the tunnel:
•
•
•
•
You are setting one bit for each color; however, the sample output shows multiple bits at the same time. For example, you can configure red and black colors on GigabitEthernet0/4/1/3 from the interface command. The sample output from the show mpls traffic-eng link-management interfaces command shows that the Attributes field is set to 0x21, which means that there are 0x20 and 0x1 bits on the link.
Task ID
Examples
The following example shows how to configure the tunnel affinity and mask:
RP/0/RP0/CPU0:router# configureRP/0/RP0/CPU0:router(config)# interface tunnel-te 1RP/0/RP0/CPU0:router(config-if)# affinity 0101 mask 303The following example shows that a link is eligible for CSPF if it has at least red color. The link can have any additional colors.

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.
Currently, the only way to forward traffic over a tunnel is accomplished using the autoroute announce command or static routes command.
When you configure more than one IGP, the tunnel is announced to the IGP used to find the path to the tunnel destination.
By default, the route metric of the tunnel path to the destination equals the route metric of the shortest IGP path to that destination when autoroute announce is configured.
Task ID
Examples
The following example shows how to configure IGP to use the tunnel in its enhanced SPF calculation when the tunnel is up:
RP/0/RP0/CPU0:router# configureRP/0/RP0/CPU0:router(config)# interface tunnel-te 1RP/0/RP0/CPU0:router(config-if)# autoroute announceRelated Commands

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.
Backup bandwidth can be limited or unlimited or specific to a global pool, sub-pool, or non-specific any-pool. Backup with backup-bw in global-pool protects global-pool LSPs only; backup-bw in sub-pool protects sub-pool LSPs only.
Backup tunnels configured with limited backup bandwidth (from any/global/sub pool) are not assigned to protect LSPs configured with zero signaled bandwidth.
Backup bandwidth provides bandwidth protection for fast reroute (FRR). Bandwidth protection for FRR supports DiffServ-TE with two bandwidth pools (class-types).
Class-type 0 is strictly equivalent to global-pool; class-type 1 is strictly equivalent to sub-pool bandwidth using the Russian Doll Model (RDM).
When using the backup bandwidth unlimited configuration under the backup tunnel interface with multiple backup tunnels, load sharing for the backup assignment uses the primary LSP bandwidth.
Task ID
Examples
The following example shows how to configure backup tunnel 1 for use only by LSPs that take their bandwidth from the global pool (class-type 0 tunnels). Backup tunnel 1 does not provide bandwidth protection.
RP/0/RP0/CPU0:router(config)# interface tunnel-te 1RP/0/RP0/CPU0:router(config-if)# backup-bw global-pool unlimitedorRP/0/RP0/CPU0:router(config)# interface tunnel-te 1RP/0/RP0/CPU0:router(config-if)# backup-bw unlimited class-type 0In the following example, backup tunnel 2 is used by LSPs that take their bandwidth from the sub-pool (class-type 1 tunnels) only. Backup tunnel 2 provides bandwidth protection for up to 1000 units.

bw-limit (MPLS-TE)
To configure the minimum and maximum automatic bandwidth to be set on a tunnel, use the bw-limit command in MPLS-TE automatic bandwidth interface configuration mode. To disable this feature, use the no form of this command.
bw-limit {min bandwidth} {max bandwidth}
no bw-limit
Syntax Description
Defaults
min: 0 kbps
max: 4294967295 kbps
Command Modes
MPLS-TE automatic bandwidth interface configuration
Command History
Release 3.8.0
This command was introduced on the Cisco CRS-1 and Cisco XR 12000 Series Router.
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.
Both the min and max keywords must be configured.
The bw-limit command automatically sets the minimum bandwidth to the default value of 0. Or the bw-limit command automatically sets the maximum to the default value of 4294967295 kbps.
If the value of the min keyword is greater than the max keyword, the bw-limit command is rejected. If you configure and modify the minimum or maximum bandwidth while the automatic bandwidth is already running, the next bandwidth application for that tunnel is impacted. For example, if the current tunnel requested bandwidth is 30 Mbps and the minimum bandwidth is modified to 50 Mbps, the next application sets the tunnel bandwidth to 50 Mbps.

There are two types of MPLS-TE tunnels:
•
•
At the configuration level, you cannot tell the difference between a packet MPLS or a GMPLS-TE tunnel. Because packet TE tunnels are unidirectional while GMPLS tunnels are bidirectional, you can identify the optical GMPLS tunnel by identifying the bidirectional configuration.
The GMPLS-TE tunnel requires that you specify the endpoint and transit switching capability so that the path computation module can determine the links that the tunnel can traverse.
The transit switching capability describes the switching capability of the LSP region that the tunnel crosses. The endpoint switching capability describes the switching capability and encoding required for the tunnel interface associated with the two ends of the bidirectional tunnel (namely, active and passive side).
Finally, for GMPLS functionality to work, you must configure the direction and switching commands.

When a protected link used by the fast-reroutable label switched path (LSP) fails, the traffic is rerouted to a previously assigned backup tunnel. Configuring FRR on the tunnel informs all the nodes that the LSP is traversing that this LSP desires link/node/bandwidth protection.
You must allow sufficient time after an RP failover before triggering FRR on standby RPs in order to synchronize with the active RP (verified using the show redundancy command). All TE tunnels must be in the recovered state and the database must be in the ready state for all ingress and egress line cards. To verify this information, use the show mpls traffic-eng tunnels and show mpls traffic-eng fast-reroute database commands.

To return to the default behavior, use the no form of this command.
fast-reroute timers promotion interval
no fast-reroute timers promotion
Syntax Description
interval
Interval (in seconds) between scans to determine if a label switched path (LSP) should use a new, better backup tunnel. Range is 0 to 604800. A value of 0 disables backup tunnel promotions.
Defaults
interval: 300 seconds (5 minutes)

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.
Setting the interval to a low value puts more load on the CPU, because it has to scan all protected LSPs more frequently. It is not recommended that the timer be configured below the default value of 300 seconds.
Pacing mechanisms have been implemented to distribute the load on the CPU when backup promotion is active. Because of this, when a large number of protected LSPs are promoted, some delay is noticeable in backup promotion. If the promotion timer is configured to a very low value (depending on the number of protected LSPs) some protected LSPs may never get promoted.
To disable the timer, set the value to zero.
Task ID
Examples
The following example shows how to specify that LSPs are scanned every 600 seconds (10 minutes) to determine if they should be promoted to a better backup tunnel:

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.
You cannot include or exclude addresses from an IP explicit path unless explicitly configured using the exclude-address keyword.
Use the exclude-address keyword only after entering the explicit path configuration mode.
If you use the exclude-address keyword and specify the IP address of a link, the constraint-based routine does not consider that link when it sets up MPLS-TE paths. If the excluded address is a flooded MPLS-TE router ID, the constraint-based shortest path first (SPF) routine does not consider that entire node.
Note
MPLS-TE accepts IP explicit paths composed of all excluded addresses configured using the exclude-address keyword.

Use the policy-class command to enable policy-based tunnel selection (PBTS). See Cisco IOS XR MPLS Configuration Guide for more information on PBTS.
To display the configured PBTS policy-class value, use the show mpls traffic-eng tunnels command.
To display information about PBTS configuration, use the show cef and show cef hardware commands in Cisco IOS XR IP Addresses and Service Command Reference.
The default class is not associated with any of the existing classes from 0 to 7. For a class of traffic that does not have a respective class tunnel, the forwarding place uses the available default tunnels and IGP and LDP paths can carry that class of traffic. The default traffic stream is load balanced over the default tunnels and IGP and LDP paths. Up to eight default tunnels are used to forward default traffic towards the destination.

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.
When an LSP is signaled and an interface does not currently have enough bandwidth available for that LSP, the call admission software (if necessary) preempts lower-priority LSPs to admit the new LSP. Accordingly, the new LSP priority is the setup priority and the existing LSP priority is the hold priority. The two priorities make it possible to signal an LSP with a low setup priority (so that the LSP does not preempt other LSPs on setup) and a high hold priority (so that the LSP is not preempted after it is established). Setup priority and hold priority are typically configured to be equal, and setup priority cannot be numerically smaller than the hold priority.

A device with Multiprotocol Label Switching traffic engineering (MPLS-TE) tunnels periodically examines tunnels with established LSPs to discover if more efficient LSPs (paths) are available. If a better LSP is available, the device signals the more efficient LSP; if the signaling is successful, the device replaces the older LSP with the new, more efficient LSP.
Sometimes the slower router-point nodes may not yet utilize the new label's forwarding plane. In this case, if the headend node replaces the labels quickly, it can result in brief packet loss. By delaying the cleanup of the old LSP using the reoptimize timers delay cleanup command, packet loss is avoided.

If the command is entered without the notification-option argument, all MPLS-TE notification types are enabled.
SNMP notifications can be sent as either traps or inform requests.
The snmp-server enable traps mpls traffic-eng command enables both traps and inform requests for the specified notification types. To specify whether the notifications should be sent as traps or informs, use the snmp-server host command and specify the keyword trap or informs.
If you do not enter the snmp traps mpls traffic-eng command, no MPLS-TE notifications controlled by this command are sent. To configure the router to send these MPLS-TE SNMP notifications, you must enter at least one snmp enable traps mpls traffic-eng command. If you enter the command with no keywords, all MPLS-TE notification types are enabled. If you enter the command with a keyword, only the notification type related to that keyword is enabled. To enable multiple types of MPLS-TE notifications, you must issue a separate snmp traps mpls traffic-eng command for each notification type and notification option.
The snmp traps mpls traffic-eng command is used in conjunction with the snmp host command. Use the snmp host command to specify which host or hosts receive MPLS-TE SNMP notifications. To send notifications, you must configure at least one snmp host command.
For a host to receive an MPLS-TE notification controlled by this command, both the snmp traps mpls traffic-eng command and the snmp host command for that host must be enabled.

A router at the headend for TE tunnels can receive a Resource Reservation Protocol (RSVP) No Route error message before the router receives a topology update from the IGP routing protocol announcing that the link is down. When this happens, the headend router ignores the link in subsequent tunnel path calculations to avoid generating paths that include the link and are likely to fail when signaled. The link is ignored until the router receives a topology update from its IGP or a link holddown timeout occurs. Use the topology holddown sigerr command to change the link holddown time from its 10-second default value.
