Function

The mpls te ordinary-lsp-constraint command allows you to use a CR-LSP attribute template to set up an ordinary backup CR-LSP.

Usage Guidelines

A maximum number of three CR-LSP attribute templates can be configured to set up an ordinary backup CR-LSP. The ordinary backup CR-LSPs must be consistent with the primary CR-LSP in the following attributes:

Setup priority
Holding priority
Bandwidth type

Among the three CR-LSP attribute templates corresponding to a primary CR-LSP and ordinary backup CR-LSP, only one CR-LSP attribute template can be specified with the dynamic parameter.

The parameter number is used to number each CR-LSP attribute template. The CR-LSP attribute templates are each applied by the system in sequence of ascending number until an ordinary backup CR-LSP is set up.

Before running the mpls te ordinary-lsp-constraint command, you must run the mpls te primary-lsp-constraint command to use a CR-LSP attribute template to set up a primary CR-LSP.
When the mpls te ordinary-lsp-constraint command is run to help set up an ordinary backup CR-LSP, the record route function is automatically enabled.

Example

# Use the attribute template named t3 to set up an ordinary backup CR-LSP.
