The value of vRtrMplsLspPathOperFRNodeProtect specifies
whether the currently operational LSP path has node protection
enabled or disabled.
When make-before-break functionality for the LSP is enabled and if the
LSP node protection setting is changed, the resources allocated to the
existing LSP paths will not be released until a new path with the new
settings has been established. While a new path is being signaled, the
administrative value and the operational values of the path may
differ. The value of vRtrMplsLspFRNodeProtect specifies the node
protection setting for the new LSP path trying to be established
whereas the value of vRtrMplsLspPathOperFRNodeProtect specifies the
node protection setting for the existing LSP path.
