This reports the upper boundary of the administratively configured dynamic label range, marking the top of the label block available for RSVP-TE/LDP-signaled LSPs on this device. Together with the dynamic start value, it tells an admin exactly how much automatic-signaling label capacity is provisioned, which matters when a network is scaling up the number of dynamically established tunnels or pseudowires and risks exhausting the pool. If dynamic label allocation failures start appearing in logs, checking whether usage is approaching this end boundary is a natural first diagnostic step.
