add hop

Function

The add hop command adds a specified node on an MPLS TE explicit path.

Format

add hop ip-address1 [ include [ [ loose | strict ] | [ incoming | outgoing ] ] * | exclude ] { after | before } ip-address2

Parameters

Parameter Description Value
ip-address1 Specifies the IP address of the added node. The value is in dotted decimal notation.
include [ [ loose | strict ] | [ incoming | outgoing ] ] * Specifies the node with an IP address ip-address1 on the explicit path.
  • strict: indicates that the node is added in strict mode. The node of ip-address1 is directly connected to the node of ip-address2.
  • loose: indicates that the node is added in loose mode. The node of ip-address1 may not be directly connected to the node of ip-address2.
  • incoming: indicates that the ip-address1 is the IP address of an inbound interface of a new-added node.
  • outgoing: indicates that the ip-address1 is the IP address of an outbound interface of a new-added node.
 By default, an explicit path is added in include strict mode.
exclude Excludes the node of ip-address1 from the explicit path. -
after Indicates that the node of ip-address1 is added after the node of ip-address2. -
before Indicates that the node of ip-address1 is added before the node of ip-address2. -
ip-address2 Specifies the IP address of an interface or the Router ID of a node on the explicit path. The value is in dotted decimal notation.

Views

Explicit path view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

The following commands are used to adjust nodes on a created explicit path:

  • The add hop command is used to add a node to the explicit path.
  • The modify hop command is used to delete a node from the explicit path and replace the node with a specified node.
  • The delete hop command is used to delete a node from the explicit path.

Prerequisites

The next hop command must have been run to specify a next-hop IP address before the add hop command is run.

Follow-up Procedure

Run the display explicit-path command to view information about the explicit path.

Precautions

A node can be added to an explicit path using the add hop command only when the following conditions are met:
  • ip-address2 is the IP address of a node that exists on the explicit path.
  • If an explicit path over which a TE tunnel has been established is modified, the make-before-break mechanism is triggered, and a CR-LSP is reestablished without traffic loss.

Example

# Exclude the next hop of 10.2.2.2 after 10.1.1.1 from the explicit path named p1.

<HUAWEI> system-view
[HUAWEI] mpls
[HUAWEI-mpls] mpls te
[HUAWEI-mpls] quit
[HUAWEI] explicit-path p1
[HUAWEI-explicit-path-p1] next hop 10.1.1.1
[HUAWEI-explicit-path-p1] add hop 10.2.2.2 exclude after 10.1.1.1

affinity property

Function

The affinity property command configures the affinity property for a CR-LSP attribute template.

The undo affinity property command deletes the affinity property from a CR-LSP attribute template.

By default, no affinity property for a CR-LSP attribute template is configured.

Format

affinity property affinity-value [ mask mask-value ]

undo affinity property

Parameters

Parameter Description Value
affinity-value Specifies the value of the affinity property. The value ranges from 0x0 to 0xFFFFFFFF, in hexadecimal format. By default, the affinity value is 0.
mask mask-value Specifies the mask value of an affinity property. Then an operation is performed between the mask value and the affinity property value, and the result indicates the bits of the affinity property to be checked. The value ranges from 0x0 to 0xFFFFFFFF, in hexadecimal format. By default, the value is 0.

Views

Default Level

2: Configuration level

Usage Guidelines

The undo bandwidth command can be used to delete the bandwidth of all CTs or a specified CT:

  • undo bandwidth all: deletes all configured bandwidth.
  • undo bandwidth { ct0 | ct1 }: deletes the bandwidth of the specified CT configured on the current TE tunnel.

Example

# Configure the bandwidth of an LSP of CT0 as 20 kbit/s in the CR-LSP attribute template.

<HUAWEI> system-view
[HUAWEI] lsp-attribute lsp-attribute-name
[HUAWEI-lsp-attribute-lsp-attribute-name] bandwidth ct0 20

bfd bind mpls-te

Function

The bfd bind mpls-te command configures BFD to monitor TE tunnels, or the primary or backup LSP bound to a TE tunnel.

The undo bfd command deletes a specified BFD session.

By default, no TE tunnel applies BFD.

Format

bfd cfg-name bind mpls-te interface tunnel interface-number [ te-lsp [ backup ] ]

undo bfd cfg-name

Parameters

Parameter Description Value
cfg-name Specifies the BFD configuration name. The value is a string of 1 to 15 case-insensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
interface tunnel interface-number Specifies the interface number of the TE tunnel bound to a BFD session. -
te-lsp [ backup ] Indicates that BFD monitors the LSP bound to the TE tunnel.
  • If backup is not selected, BFD monitors the primary LSP bound to the TE tunnel.
  • If backup is selected, BFD monitors the backup LSP bound to the TE tunnel.
 -

Views

System view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

You can run the bfd bind mpls-te command to configure BFD to monitor TE tunnels, or the primary or backup LSP bound to a TE tunnel.

Prerequisites

Before configuring BFD to monitor TE tunnels, the following tasks must have been completed:

  • BFD has been enabled globally using the bfd command.

  • An MPLS TE tunnel interface has been configured.

Precautions

BFD can monitor a TE tunnel and the primary or backup LSP bound to the TE tunnel.

  • If BFD is configured to monitor the primary or backup LSP bound to a TE tunnel, a BFD session cannot be created if the LSP status is Down.

  • If the tunnel status is Down when BFD is configured to monitor a TE tunnel, the BFD session can still be created, but its status is Down.

    Multiple LSPs can be bound to a TE tunnel. When BFD detects the tunnel, the BFD session will go Down only if all LSPs bound to the TE tunnel fail.

NOTE:

MPLS OAM and BFD cannot be configured together for one TE tunnel or CR-LSP.

Example

# Configure BFD to detect the primary LSP bound to the TE tunnel.

<HUAWEI> system-view
[HUAWEI] bfd 1to4rsvp bind mpls-te interface Tunnel 1 te-lsp 
[HUAWEI-bfd-lsp-session-1to4rsvp]

# Configure BFD to detect the backup LSP bound to the TE tunnel.

<HUAWEI> system-view
[HUAWEI] bfd 1to4backup bind mpls-te interface Tunnel 1 te-lsp backup
[HUAWEI-bfd-lsp-session-1to4backup]

bypass-attributes

Function

The bypass-attributes command configures bypass CR-LSP attributes in a CR-LSP attribute template.

The undo bypass-attributes command deletes bypass CR-LSP attributes from a CR-LSP attribute template.

By default, no bypass CR-LSP attributes are configured.

Format

bypass-attributes { bandwidth bandwidth | priority setup_priority_value [ hold_priority_value ] }*

undo bypass-attributes

Parameters

Parameter Description Value
bandwidth bandwidth Specifies the bandwidth value assigned to a bypass CR-LSP.
NOTE:

The function of bandwidth value assigned to a bypass CR-LSP does not take effect on the devices.

 An integer ranging from 1 to 4000000000, in kbit/s. By default, the bandwidth is 0 kbit/s.
priority setup_priority_value Specifies the setup priority of a bypass CR-LSP. An integer ranging from 0 to 7. The smaller the value, the higher the priority. By default, the setup priority is 7.
hold_priority_value Specifies the holding priority of the bypass CR-LSP. An integer ranging from 0 to 7. The smaller the value, the higher the priority. By default, the holding priority is 7.

Views

LSP attribute view

Default Level

2: Configuration level

Usage Guidelines

To configure the bypass-attributes command in the CR-LSP attribute template, note the following preconditions:

  • The fast-reroute bandwidth command must be configured in the CR-LSP attribute template, and the bandwidth of the bypass CR-LSP must be less than or equal to that of the primary CR-LSP.

  • The bandwidth of the bypass CR-LSP must be less than or equal to that of the CR-LSP attribute template.

  • The values of the setup and holding priority of the CR-LSP attribute template must be less than or equal to those of the bypass CR-LSP.

Example

# Configure the bypass CR-LSP attributes in the CR-LSP attribute template.

<HUAWEI> system-view
[HUAWEI] lsp-attribute lsp-attribute-name
[HUAWEI-lsp-attribute-lsp-attribute-name] fast-reroute bandwidth
[HUAWEI-lsp-attribute-lsp-attribute-name] bypass-attributes bandwidth 30 priority 5 5

commit (LSP attribute view)

Function

The commit command commits the configurations of the CR-LSP attribute template.

Format

commit

Parameters

None

Views

LSP attribute view

Default Level

2: Configuration level

Usage Guidelines

When the CR-LSP attribute template is modified, if the commands that conflict with the CR-LSP attribute template are configured on a tunnel interface, the configurations of the CR-LSP attribute template cannot be committed.

When the CR-LSP attribute template is applied by a tunnel, you can modify the tunnel attributes by modifying the configurations of the CR-LSP attribute template. Different modifications in the CR-LSP attribute template have different impacts on the setup of the tunnel. If the priorities of the CR-LSP attribute template are modified, Break-Before-Make (BBM) is performed on the tunnel. If the Make-Before-Break (MBB) attribute of the CR-LSP attribute template is modified, MBB may be performed on the tunnel.

Example

# Configure the CR-LSP attribute template and commit relevant configurations.

<HUAWEI> system-view
[HUAWEI] lsp-attribute lsp-attribute-name
[HUAWEI-lsp-attribute-lsp-attribute-name] hop-limit 15
[HUAWEI-lsp-attribute-lsp-attribute-name] commit

delete hop

Function

The delete hop command deletes a specified node from an MPLS TE explicit path.

Format

delete hop ip-address

Parameters

Parameter Description Value
ip-address Specifies the IP address of an interface on a node. In dotted decimal notation.

Views

Explicit path view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

The following commands are used to adjust nodes on a created explicit path:

  • The add hop command is used to add a node to the explicit path.
  • The modify hop command is used to delete a node from the explicit path and replace the node with a specified node.
  • The delete hop command is used to delete a node from the explicit path.

Follow-up Procedure

Run the display explicit-path command to view information about the explicit path.

Precautions

A node can be deleted from an explicit path using the delete hop command only when the following conditions are met:
  • The node must exist on the explicit path
  • If an explicit path over which a TE tunnel has been established is modified, the make-before-break mechanism is triggered, and a CR-LSP is reestablished without traffic loss.

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

Usage Scenario

You can run the display mpls te tunnel-interface last-error command on the ingress to view the error of a local node or the error carried in an RSVP PathErr message sent by a downstream node. The errors can be as follows:
  • CSPF computation fails.

  • RSVP times out.

  • One or more LSPs are deleted during RSVP GR smooth.
  • One or more LSPs are deleted during RSVP aging.
  • RSVP GR fails to be triggered.

Precautions

The display mpls te tunnel-interface last-error command shows the last 20 recorded errors of each TE tunnel and LSP on which the errors occur, including errors about the primary CR-LSP, modified LSP, and backup CR-LSP.

If an RSVP PathErr message sent by a downstream node carries the error information, the ErroInfo field in the command output shows the IP address of the faulty downstream node and the cause of the error. If an error occurs on the ingress, the command output only shows the cause of the error.

Example

# Display information about the last errors of Tunnel1.

Usage Guidelines

Usage Scenario

The display mpls te tunnel path command displays information about the path of an MPLS TE tunnel.

If no tunnel name is specified, information about all MPLS TE tunnels' path attributes is displayed.

When a Huawei device is interconnected with a non-Huawei device and the RRO information carried in the packet sent by the non-Huawei device is incomplete, the RRO information can be complemented using the display mpls te tunnel path expanded command on the Huawei device to display the information about the entire LSP path.

Precautions

The system can record and display the paths only after the mpls te record-route command is configured.

Example

# Display information about path attributes of all MPLS TE tunnels.

modify hop

Function

The modify hop command modifies the IP address of a hop on an explicit path.

Format

modify hop ip-address1 ip-address2 [ include [ [ loose | strict ] | [ incoming | outgoing ] ] * | exclude ]

Parameters

Parameter Description Value
ip-address1 ip-address2 Changes ip-address1 to ip-address2 on an explicit path. The value is in dotted decimal notation.
include [ [ loose | strict ] | [ incoming | outgoing ] ] * Indicates that the explicit path must pass through the modified node on the explicit path.
  • strict: indicates the strict explicit path. The modified node must be directly connected to the previous node.
  • loose: indicates the loose explicit path. The modified node can be not directly connected to the previous node.
  • incoming: indicates that the ip-address2 is the IP address of an inbound interface of the modified node.
  • outgoing: indicates that the ip-address2 is the IP address of an outbound interface of the modified node.
 By default, a node is added to an explicit path in include strict mode.
exclude Indicates that the LSP set up along an explicit path excludes the modified link or node. -

Usage Guidelines

Usage Scenario

The following commands are used to adjust nodes on a created explicit path:

  • The add hop command is used to add a node to the explicit path.
  • The modify hop command is used to delete a node from the explicit path and replace the node with a specified node.
  • The delete hop command is used to delete a node from the explicit path.

Prerequisites

A next-hop IP address has been configured using the next hop command.

Follow-up Procedure

Run the display explicit-path command to view information about the explicit path.

Precautions

A node can be modified on an explicit path using the modify hop command only when the following conditions are met:
  • ip-address2 must not be a next-hop IP address of an existing node on the explicit path.
  • If an explicit path over which a TE tunnel has been established is modified, the make-before-break mechanism is triggered, and a CR-LSP is reestablished without traffic loss.

Example

# Modify IP address of a node along the explicit path from 10.1.1.9 to 10.2.2.9.

mpls-te enable

Function

The mpls-te enable command enables the MPLS TE feature in the current OSPF area.

The undo mpls-te command disables the MPLS TE feature in the current OSPF area.

OSPF area does not support MPLS TE by default.

Format

mpls-te enable [ standard-complying ]

undo mpls-te

Parameters

Parameter Description Value
standard-complying Accepts only LSAs in the standard format. This means that an LSA is rejected if it has more than one Top level TLV. -

mpls autobypass-tunnel-number threshold-alarm

Function

The mpls autobypass-tunnel-number threshold-alarm command configures the conditions that trigger the threshold-reaching alarm and its clear alarm for Auto bypass tunnel interfaces.

The undo mpls autobypass-tunnel-number threshold-alarm command restores the default settings.

By default, the upper alarm threshold is 80%, and the lower alarm threshold is 75%.

Format

mpls autobypass-tunnel-number threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

undo mpls autobypass-tunnel-number threshold-alarm

Parameters

Parameter Description Value
upper-limit upper-limit-value

Specifies the upper alarm threshold for the proportion of configured Auto bypass tunnel interfaces to all supported ones.

 The value is an integer ranging from 1 to 100, represented in percentage. Using a value larger than 95 is not recommended. Using the default value 80 is recommended.
lower-limit lower-limit-value

Specifies the lower alarm threshold for the proportion of configured Auto bypass tunnel interfaces to all supported ones.

 The value is an integer ranging from 1 to 100, represented in percentage. The value must be smaller than the value of upper-limit-value. Using the default value 75 is recommended.

Usage Guidelines

Usage Scenario

If the number of Auto bypass tunnel interfaces reaches a specified upper limit, new Auto bypass tunnel interfaces cannot be configured due to insufficient resources. To alert the administrator in operation and maintenance, enable a device to generate an alarm when the proportion of configured Auto bypass tunnel interfaces to all supported ones reaches a specified upper alarm threshold. The following parameters can be configured in the mpls autobypass-tunnel-number threshold-alarm command:

  • upper-limit-value: upper alarm threshold. If the proportion of configured Auto bypass tunnel interfaces to all supported ones reaches the upper alarm threshold, an alarm can be generated.
  • lower-limit-value: lower alarm threshold. If the proportion of configured Auto bypass tunnel interfaces to all supported ones falls below the lower alarm threshold, a clear alarm can be generated.

Precautions

  • If the mpls autobypass-tunnel-number threshold-alarm command is run more than once, the latest configuration overrides the previous one.

  • The mpls autobypass-tunnel-number threshold-alarm command only configures the trigger conditions for an alarm and its clear alarm. Although trigger conditions are met, the alarm and its clear alarm can be generated only after the snmp-agent trap enable feature-name mpls_lspm trap-name { hwmplsresourcethresholdexceed | hwmplsresourcethresholdexceedclear } command is run to enable the device to generate an MPLS resource insufficiency alarm and its clear alarm.

# Configure conditions that trigger the threshold-reaching alarm and its clear alarm for Auto bypass tunnel interfaces.

mpls bfd-te-number threshold-alarm

Function

The mpls bfd-te-number threshold-alarm command configures the conditions that trigger the threshold-reaching alarm and its clear alarm for dynamic BFD sessions for TE.

The undo mpls bfd-te-number threshold-alarm command restores the default settings.

By default, the upper alarm threshold is 80%, and the lower alarm threshold is 75%.

Format

mpls bfd-te-number threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value

undo mpls bfd-te-number threshold-alarm

Parameters

Parameter Description Value
upper-limit upper-limit-value

Sets the upper alarm threshold for the proportion of established dynamic BFD sessions for TE to all supported ones.

 The value is an integer ranging from 1 to 100, represented in percentage. Using a value larger than 95 is not recommended. Using the default value 80 is recommended.
lower-limit lower-limit-value

Sets the lower alarm threshold for the proportion of established dynamic BFD sessions for TE to all supported ones.

 The value is an integer ranging from 1 to 100, represented in percentage. The value must be smaller than the value of upper-limit-value. Using the default value 75 is recommended.
