Auto Complete at End Time

Automatically completes the maintenance event and brings the elements back up at the specified end time. If the check box is not selected, you must manually complete the maintenance event after it finishes.

When a maintenance event is completed, it brings the maintenance elements back to an Up state, ready for path reoptimization. The affected LSPs are then rerouted to optimal paths unless you have deselected Reoptimize Tunnels Upon Completion.

Reoptimize Tunnels upon Completion

Reoptimizes the LSPs that were affected by the maintenance event when the maintenance event is completed. When you toggle the Reoptimize Tunnels upon Completion option, that behavior is disabled. This allows you to use a maintenance event to temporarily disable a link.
