mpls te bypass-attributes (Tunnel interface view)

Function

The mpls te bypass-attributes command configures bypass tunnel attributes.

The undo mpls te bypass-attributes command restores the default bypass tunnel attributes.

By default, no bypass tunnel attributes are configured.

Format

mpls te bypass-attributes [ bandwidth bandwidth ] [ priority setup-priority [ hold-priority ] ]

undo mpls te bypass-attributes

Parameters

Parameter	Description	Value
bandwidth bandwidth	Specifies the bandwidth value for a bypass tunnel.	The value is an integer ranging from 0 to 4000000000, and the actual maximum value is the maximum reservable bandwidth of a primary tunnel, in kbit/s. After bandwidth protection is enabled, the default bypass tunnel bandwidth is equal to the primary tunnel bandwidth.
priority setup-priority	Specifies the setup priority.	The value is an integer ranging from 0 to 7. The smaller the value, the higher the priority. The default setup priority is 7.
hold-priority	Tunnel hold priority value, the default is 7.	The value is an integer ranging from 0 to 7. A holding priority value must be less than or equal to a setup priority value. The smaller the value, the higher the priority. The default value is the same as the configured setup priority value.

Parameter

Description

Value

bandwidth bandwidth

Specifies the bandwidth value for a bypass tunnel.

The value is an integer ranging from 0 to 4000000000, and the actual maximum value is the maximum reservable bandwidth of a primary tunnel, in kbit/s. After bandwidth protection is enabled, the default bypass tunnel bandwidth is equal to the primary tunnel bandwidth.

priority setup-priority

Specifies the setup priority.

The value is an integer ranging from 0 to 7. The smaller the value, the higher the priority. The default setup priority is 7.

hold-priority

Tunnel hold priority value, the default is 7.

The value is an integer ranging from 0 to 7. A holding priority value must be less than or equal to a setup priority value. The smaller the value, the higher the priority. The default value is the same as the configured setup priority value.

Usage Guidelines

Usage Scenario

The mpls te bypass-attributes command is used to configure constraints for setting up a bypass tunnel for a primary tunnel. A path satisfying the following constraints can be set up:

Its bandwidth value is greater than or equal to the value specified using the mpls te bypass-attributes bandwidth bandwidth command.
Its setup priority value is greater than or equal to the value specified using the mpls te bypass-attributes priority setup-priority command.
Its holding priority value is greater than or equal to the value specified using the mpls te bypass-attributes priority hold-priority command.

Prerequisites

FRR has been enabled using the mpls te fast-reroute command.

Precautions

The bypass tunnel bandwidth cannot exceed the primary tunnel bandwidth. The setup priority of a bypass tunnel must be less than or equal to the holding priority. Both must be less than or equal to those of the primary tunnel.

Example

# Set the bandwidth of the bypass tunnel to 2048 kbit/s, the setup priority to 4, and the holding priority to 3.
