[no] path path-name

config>router>mpls

This command creates the path to be used for an LSP. A path can be used by multiple LSPs. A path

can specify some or all hops from ingress to egress and they can be either strict or loose. A path can

also be empty (no path-name specified) in which case the LSP is set up based on IGP (best effort)

calculated shortest path to the egress router. Paths are created in a shutdown state. A path must be

shutdown before making any changes (adding or deleting hops) to the path. When a path is shutdown,

any LSP using the path becomes operationally down.

To create a strict path from the ingress to the egress router, the ingress and the egress routers must be

included in the path statement.

The no form of this command deletes the path and all its associated configuration information. All the

LSPs that are currently using this path will be affected. Additionally all the services that are actively

using these LSPs will be affected. A path must be shutdown and unbound from all LSPs using the

path before it can be deleted. The no path path-name command will not result in any action except a

warning message on the console indicating that the path may be in use.

path-name — Specify a unique case-sensitive alphanumeric name label for the LSP path up to 32

[no] shutdown

config>router>mpls>path

This command disables the existing LSPs using this path. All services using these LSPs are affected.

Binding information, however, is retained in those LSPs. Paths are created in the shutdown state.

The no form of this command administratively enables the path. All LSPs, where this path is defined

as primary or defined as standby secondary, are (re)established.
