The user can modify the bypass LSP parameters when the configuration is adaptive. When the bypass LSP is operationally UP, then any modification of the adaptive parameters of the bypass LSP creates a new instance of the bypass LSP if it is not present. Once modifying one or more adaptive parameters, the user can commit the changes so the new instance of the bypass LSP can be try to bring it to the UP status. When the new instance of the bypass LSP is successfully UP, then a make before break switch happens from current instance of the bypass to the newly brought up instance.
To commit adaptive parameters of a bypass LSP, complete the following steps.
-
Enable the device for configuration.
-
Enable the MPLS router.
device(config)# router mpls
-
Configure the bypass LSP with the unique static bypass LSP name of
my-bypass-lsp
.
device(config-router-mpls)# bypass-lsp my-bypass-lsp
-
Enable the
commit command.
device(config-router-mpls-bypass-lsp-my-bypass-lsp)# commit
Example
The following example combines the steps above to configure a static bypass LSP with a unique bypass LSP name of
my-bypass-lsp
and the
commit command is enabled.
device>configure
device(config)# router mpls
device(config-router-mpls)# bypass-lsp my-bypass-lsp
device(config-router-mpls-bypass-lsp-my-bypass-lsp)# commit
