Performing a commit for an LSP configuration command
For LSP configuration commands to take effect, either an explicit or implicit commit must be
performed. These are performed as shown in the following:
Performing an explicit commit
The user can perform an explicit commit within the configuration of a specified LSP using the
commit command. The following example demonstrates the creation of an LSP named samplelsp
and its primary and secondary paths. After the configuration is entered, the commit command is
executed to activate the configuration.
Brocade(config)# router mpls
Brocade(config-mpls)# lsp samplelsp
Brocade(config-mpls-lsp-samplelsp)# primary-path pathprimary
Brocade(config-mpls-lsp-samplelsp)# secondary-path pathsecondarya
Brocade(config-mpls-lsp-samplelsp)# secondary-path pathsecondaryb
Brocade(config-mpls-lsp-samplelsp)# select manual pathsecondaryb
Brocade(config-mpls-lsp-samplelsp)# commit
Syntax: [no] commit
The reoptimize command is another type of explicit commit.
Using the reoptimize command, the user can activate all pending LSP configuration changes for
specified LSP or use the all option to activate all pending LSP configuration changes for all of the
LSPs configured on the router. Configuration of this command is described in
.
Performing an implicit commit
MPLS allows the user to modify the configurable parameters for RSVP LSPs while the LSP is
operational. After modifying the parameters for an operational LSP, the user must execute the
commit command to apply the changes. Applying these configuration changes requires a new
instance of the LSP to be signaled with a modified or new set of parameters, also known as
make-before-break. Once the new instance of the LSP is up, the old instance is removed.
