Configuring an LSP
Perform this task to configure an LSP for an explicit path. Path protection is enabled on a tunnel by adding
an additional path option configuration at the active end. The path can be configured either explicitly or
dynamically.
When the dynamic option is used for both working and protecting LSPs, CSPF extensions are used to
determine paths with different degrees of diversity. When the paths are computed, they are used over the
lifetime of the LSPs. The nodes on the path of the LSP determine if the PSR is or is not for a given LSP.
This determination is based on information that is obtained at signaling.

DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Configures an MPLS-TE tunnel interface for GMPLS interfaces.
interface tunnel-gte number
Example:
RP/0/RP0/CPU0:router(config)# interface
Step 2
tunnel-gte 1
Specifies a primary or secondary IPv4 address for an interface.
ipv4 address ipv4-address mask or ipv4
unnumbered type interface-path-id
Step 3

Network mask can be a four-part dotted decimal address. For
example, 255.0.0.0 indicates that each bit equal to 1 means
