Allows you to specify the amount of time to delay the tear down of old paths after the router has switched traffic to new optimized paths. This delay timer starts when the timer specified by the optimize-switchover-delay statement has elapsed, which is typically 30 seconds, and at the start of the next retry sequence (in other words, the delay is not an absolute countdown of the seconds configured here).
You only need to configure this statement on routers acting as the ingress for the affected LSPs (you do not need to configure this statement on transit or egress routers). The specified delay helps to ensure that old paths are not torn down before all routes have been switched over to the new optimized paths.
Default: 60 to 90 seconds
Range: 0 through 65,535 seconds
