The value of vRtrMplsP2mpInstSetupPriority indicates the setup
priority to use when insufficient bandwidth is available to setup
a P2MP 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 P2MP 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 vRtrMplsP2mpInstHopLimit bit in vRtrMplsP2mpInstInheritance
is cleared (0), the value returned to a GET request is inherited
from vRtrMplsLspHopLimit.
