Usage Guidelines

Usage Scenario

Assume that an existing ordinary backup CR-LSP has been set up using a lower-priority attribute template. When the lower-priority attribute template is locked, the system does not attempt to use a higher-priority attribute template to set up a new ordinary backup CR-LSP, avoiding unnecessary traffic switchover.

Prerequisites

An ordinary backup CR-LSP has been set up using a CR-LSP attribute template by running the mpls te ordinary-lsp-constraint command.

Precautions

This command is valid only for an ordinary backup CR-LSP that is set up using a CR-LSP attribute template.
