The value of vRtrMplsLspPathOperCspfToFrstLs specifies whether
the currently operational LSP path had CSPF to first loose hop
enabled or disabled.
When make-before-break functionality for the LSP is enabled
and if the LSP CSPF to First Loose Hop 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 vRtrMplsLspCspfToFirstLoose specifies the CSPF to First
Loose Hop setting for the new LSP path trying to be established
whereas the value of vRtrMplsLspPathOperCspfToFrstLs specifies
the CSPF to First Loose Hop setting for the existing LSP path.
