The value of vRtrMplsLspPathOperRecordLabel specifies whether
the currently operational LSP path is recording or not
recording the label allocated at each traversed node.
When make-before-break functionality for the LSP is enabled and
if the path label recording 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 label recording setting of the path may
differ. The value of vRtrMplsLspPathRecordLabel specifies the
label recording setting for the new LSP path trying to be
established whereas the value of vRtrMplsLspPathOperRecordLabel
specifies the label recording setting for the existing LSP path.
