Chapter 7: Summary of Routing Policy Configuration Statements damping Syntax damping name { disable; half-life minutes; max-suppress minutes; reuse number; suppress number; } Hierarchy Level [edit logical-systems logical-system-name policy-options], [edit policy-options] Release Information Statement introduced before Junos OS Release 7.4. Statement introduced in Junos OS Release 9.0 for EX Series switches. Description Define route flap damping properties to set on BGP routes. Options disable—Disable damping on a per-prefix basis. Any damping state that is present in the routing table for a prefix is deleted if damping is disabled. half-life minutes—Decay half-life. minutes is the interval after which the accumulated figure-of-merit value is reduced by half if the route remains stable. Range: 1 through 45 Default: 15 minutes NOTE: For the half-life, configure a value that is less than the max-suppress. max-suppress minutes—Maximum hold-down time. minutes is the maximum time that a route can be suppressed no matter how unstable it has been. Range: 1 through 720 Default: 60 minutes NOTE: For the max-suppress, configure a value that is greater than the half-life. name—Name that identifies the set of damping parameters. The name can contain letters, numbers, and hyphens (-) and can be up to 255 characters long. To include spaces in the name, enclose it in quotation marks (“ ”). reuse number—Reuse threshold. number is the figure-of-merit value below which a suppressed route can be used again.
