bypass-attributes (MPLS TE P2MP template view)

Function

The bypass-attributes command sets bypass tunnel attributes.

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

By default, the bandwidth of a bypass tunnel is equal to that of the primary tunnel, and the setup and holding priority values are both 7.

Format

bypass-attributes { bandwidth bandwidth | priority setup-priority [ hold-priority ] } ^*

undo bypass-attributes

Parameters

Parameter	Description	Value
bandwidth bandwidth	Specifies the bandwidth value for a bypass tunnel.	The value is an integer ranging from 1 to the maximum reservable bandwidth of a primary tunnel, in kbit/s. When bandwidth protection is enabled, the default bypass tunnel bandwidth is equal to the primary tunnel bandwidth.
priority setup-priority	Specifies the setup priority value.	The value is an integer ranging from 0 to 7. The smaller the value, the higher the priority. The default setup priority value is 7.
priority hold-priority	Specifies the holding priority value. The holding priority must be higher than or equal to the setup priority.	The value is an integer ranging from 0 to 7. The smaller the value, the higher the priority. The default holding priority value is 7.

Parameter

Description

Value

bandwidth bandwidth

Specifies the bandwidth value for a bypass tunnel.

The value is an integer ranging from 1 to the maximum reservable bandwidth of a primary tunnel, in kbit/s. When bandwidth protection is enabled, the default bypass tunnel bandwidth is equal to the primary tunnel bandwidth.

priority setup-priority

Specifies the setup priority value.

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

priority hold-priority

Specifies the holding priority value. The holding priority must be higher than or equal to the setup priority.

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

Usage Guidelines

Usage Scenario

A bypass tunnel is established using the configured bandwidth value. The bypass tunnel bandwidth cannot exceed the primary tunnel bandwidth. The setup priority of a bypass tunnel must be lower than or equal to the holding priority. Both of them must be lower than or equal to those of the primary tunnel.

Prerequisites

P2MP TE FRR for bandwidth protection has been enabled using the fast-reroute bandwidth command.

Example

# Set the bandwidth to 2048 kbit/s for a bypass tunnel.
