Release Information

Statement introduced before JUNOS Release 7.4.

Description

Enable the smart optimization timer. When you enable the smart optimization timer on a router, the JUNOS Software operates on the assumption that the original LSP path is preferable to any alternate or secondary path. When you enable the smart optimization timer and an LSP fails and its traffic is switched to an alternate path, the smart optimization timer starts and waits 3 minutes (this time is configurable). After 3 minutes have passed, the LSP is switched back to the original path. If the original path fails again and the LSP is switched to an alternate path again, the router waits 1 hour before attempting to switch the LSP back to its original path.

Default

The smart optimization timer is disabled by default.

Options

seconds—(Optional) Specify the number of seconds to wait before switching an LSP back to its original path.

Range: 0 through 65,535 seconds
