Auto-Deletion of Unused TE Tunnels Using a Timer-Based Mechanism

This document describes a timer-based mechanism for handling unused Traffic Engineering (TE) tunnels. When a tunnel remains inactive for a configured period, it is moved to a parked state, administratively shut down, and the associated resources are released. If the tunnel remains parked beyond a longer retention interval, it may be deleted automatically or removed through operator action, depending on local policy. This approach improves resource utilization and provides a structured lifecycle for unused TE tunnels.
