This reports the total bandwidth (kbps) configured for priority-6-class tunnels on this TE-link, near the bottom of the eight-level preemption hierarchy and typically applied to low-guarantee traffic that is among the first to be preempted if the link becomes congested. This pool being defined at all -- even a small value like 200000 kbps -- still guarantees some minimum reservable capacity to this near-lowest tier rather than leaving it with zero dedicated bandwidth. An operator reviewing link utilization would use this figure to confirm how much room exists specifically for low-priority tunnel traffic.
