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.
On PTX and MX routers the no-local-reversion
option is enabled
by default starting with Junos OS release 16.1. If you use the
no-cspf
option on these platforms with either link
protection or node-link protection enabled, you must also configure the
local-reversion
option to enure proper behavior,
