Release Information

Statement introduced before Junos OS Release 7.4.

Description

Disable constrained-path LSP computation.

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

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

Interior gateway protocol (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.
