bgp dampening
Enables BGP route-ap dampening and congures the dampening parameters.
Syntax
bgp dampening [half-life | reuse-limit | suppress-limit | max-suppress-time |
route-map-name]
Parameters
• half-life — (Optional) Enter the half-life time (in minutes) after which the penalty decreases. After the
router assigns a penalty of 1024 to a route, the penalty decreases by half after the half-life period expires, from
1 to 45.
• reuse-limit — (Optional) Enter a reuse-limit value, which compares to the apping route’s penalty value. If
the penalty value is less than the reuse value, the apping route advertises again and is not suppressed, from 1
to 20000.
•
suppress-limit — (Optional) Enter a suppress-limit value, which compares to the apping route’s penalty
value. If the penalty value is greater than the suppress value, the apping route is no longer advertised, from 1
to 20000.
• max-suppress-time — (Optional) Enter the maximum number of minutes a route is suppressed, from 1 to
255.
• route-map-name — (Optional) Enter the name of the route-map.
Defaults half-life 15; reuse-limit 750; suppress-limit 2000; max-suppress-time 60
Command Mode ROUTER-BGP-AF
Usage Information To reduce the instability fo the BGP process, setup route ap dampening parameters. After setting up the
dampening parameters, clear information on route dampening and return suppressed routes to the Active state.
You can also view statistics on route apping or change the path selection from the default deterministic mode to
non-deterministic. The no version of this command resets the value to the default.
Example
OS10(conf-router-bgpv4-af)# dampening 2 751 2001 51 map1
