Description

Disable constrained-path LSP computation.

An explicit-path LSP is one that is completely configured through operator action. Once configured, it is initiated only along the explicitly specified path.

A constrained-path LSP relies on ingress router to compute the complete path. The ingress router takes into account the following information during the computation:

• IGP topology database
• Link utilization information from extensions in the IGP link-state database
• Administrative group information from extensions in the IGP link-state database
• LSP requirements, including bandwidth, hop count, and administrative group

Constrained-path LSPs can generally avoid link failures and congested links. They also permit recomputation (therefore, a new path) during topology changes or unsuccessful setup.

Default

Constrained-path LSP computation enabled.
