MPLS Commands
path
Syntax [no] path path-name
Context config>router>mpls
Description 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.
Parameters
path-name — Specify a unique case-sensitive alphanumeric name label for the LSP path up to 32
shutdown
Syntax [no] shutdown
Context config>router>mpls>path
Description
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.
Default
shutdown
