Command History
Examples In the following example, LSPs are scanned every 2 minutes (120 seconds). The router uses this
i
nformation to consider if the LSPs should be promoted to a better backup tunnel:
Router(config)# mpls traffic-eng fast-reroute timers promotion 120
promotion seconds (Optional) Sets the interval, in seconds, between scans to determine if an
LSP should use a new, better backup tunnel. Valid values are from 0 to
604800. A value of 0 disables promotions to a better LSP.
