Damping

Damping initiates controls when routes flap. Route flapping can occur when an advertised route between nodes alternates (flaps) back and forth between two paths due to network problems which cause intermittent route failures. When a route flaps beyond a configured value (the suppress value), then that route is removed from the routing tables and routing protocols until the value falls below the reuse value.

halfLife The half life is the value for the route decay which is calculated exponentially. For example, if the half life value is configured as 15 minutes for a route with an FoM value of 2000 and no flapping incidents occur, then the FoM value is reduced to 1000 after 15 minutes and then to 500 after another 15 minutes.

maxSupression The max-suppress value is the maximum amount of time the route can stay suppressed.

reuse When the Figure of Merit (FoM) value reaches a value below the reuse threshold, the route is considered valid again.

type=long
default=0
minimum=0
maximum=20000

suppress A route is suppressed when it has flapped frequently enough to increase the Figure of Merit (FoM) value to exceed the suppress threshold limit. When the FoM value exceeds the suppress threshold limit, the route is removed from the route table or inclusion in advertisements.
