3.20.5 Configuring an MPLS LSP
When configuring an LSP, you must specify the IP address of the egress router in
the to statement. You must also specify the primary path to be used. Secondary
paths can be explicitly configured or signaled upon the failure of the primary path. All
other statements are optional.
The following displays an MPLS LSP configuration.

3.20.6 Configuring a Static LSP
An LSP can be explicitly (manually) configured. The reserved range of static LSP
labels is 32 to 1023. Static LSPs are configured on every node along the LSP path.
The label’s forwarding information includes the address of the next hop router.
Use the following CLI syntax to configure a static LSP:
CLI Syntax: config>router>mpls
static-lsp lsp-name
to ip-address
push label nexthop ip-address
no shutdown
Example: config>router# mpls
config>router>mpls# static-lsp static-LSP
