The value of vRtrMplsLspHoldPriority specifies the hold priority
to use when insufficient bandwidth is available to setup a LSP.
The setup priority is compared against the hold priority of
existing LSPs. If the setup priority is higher than the hold
priority of the established LSPs, this LSP may preempt the other
LSPs. A value of zero (0) is the highest priority and a value
of seven (7) is the lowest priority.
When the value of vRtrMplsLspPathHoldPriority is set to '-1',
the value of vRtrMplsLspHoldPriority is applied to that specific
LSP/path.
