The value of vRtrMplsLspPathOperHoldPriority specifies the
hold priority used by the operational LSP path.
When make-before-break functionality for the LSP is enabled and
if the path hold priority is changed, the resources allocated
to the existing LSP paths will not be released until a new path
with the new hold priority settings has been established. While
a new path is being signaled, the administrative value and the
operational values of the path hold priority may differ. The
value of vRtrMplsLspPathHoldPriority specifies the hold priority
for the new LSP path trying to be established whereas the value
of vRtrMplsLspPathOperHoldPriority specifies the hold priority
for the existing LSP path.
