The value of vRtrMplsLspSetupPriority specifies the setup 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 vRtrMplsLspPathSetupPriority is set to '-1',
the value of vRtrMplsLspSetupPriority is applied to that specific
LSP/path.
