optimize-timer (Protocols MPLS)
Statement introduced before Junos OS Release 7.4.
Enable periodic reoptimization of an LSP that is already set up. If topology changes occur, an existing path might become suboptimal, and a subsequent recomputation might be able to determine a better path. This feature is useful only on LSPs for which constrained-path computation is enabled; that is, for which the no-cspf statement is not configured. Also, 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).
To avoid extensive resource consumption that might result because of frequent path recomputations, or to avoid destabilizing the network as a result of constantly changing LSPs, we recommend that you either leave the timer value sufficiently large or disable the timer value.
The optimize timer is disabled.
