The value of vRtrMplsLspPathOperHopLimit specifies the maximum
hops limit used by the currently operational LSP path.
When make-before-break functionality for the LSP is enabled and if
the hop limit is changed at either LSP or LSP path level, 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 hop limit may differ. The value of
either vRtrMplsLspHopLimit or vRtrMplsLspPathHopLimit specifies
the hop limit for the new LSP path trying to be established
whereas the value of vRtrMplsLspPathOperHopLimit specifies the hop
limit for the existing LSP path.
