This object reports the end of the dynamic label range that is currently enforced, and together with the operational start-of-range value defines the real, live capacity for dynamically signaled tunnels. The size of this operational window -- end minus start -- directly bounds how many concurrent RSVP-TE-signaled LSPs the device can support before new tunnel setup requests start failing due to label pool exhaustion. For example, a live range spanning only a few thousand labels on a network trying to signal tens of thousands of dynamic LSPs would explain sporadic tunnel setup failures under load, pointing an admin toward widening this range rather than chasing a routing problem.
