Dampening (Ipv6 Address Family View) - HP FlexNetwork 3600 v2 Series Command Reference Manual

Parameters
None
Description
Use compare-different-as-med to enable the comparison of the MED for paths from peers in
different ASs.
Use undo compare-different-as-med to disable the comparison.
The comparison is disabled by default.
If several paths are available for one destination, the path with the smallest MED value is selected.
Do not use this command unless associated ASs adopt the same IGP protocol and routing selection
method.
Examples

dampening (IPv6 address family view)

Syntax
dampening [ half-life-reachable half-life-unreachable reuse suppress ceiling | route-policy
route-policy-name ] *
undo dampening
View
IPv6 address family view
Default level
2: System level
Parameters
half-life-reachable: Half-life for reachable routes, in the range of 1 to 45 minutes. By default, the
value is 15 minutes.
half-life-unreachable: Half-life for unreachable routes, in the range of 1 to 45 minutes. By default, the
value is 15 minutes.
reuse: Reuse threshold value for suppressed routes, in the range of 1 to 20000. Penalty value of a
suppressed route decreasing under the value is reused. By default, its value is 750.
suppress: Suppression threshold from 1 to 20000, which should be bigger than the reuse value.
Routes with a penalty value bigger than the threshold are suppressed. By default, it is 2000.
ceiling: Ceiling penalty value from 1001 to 20000. The value must be bigger than the suppress value.
By default, the value is 16000.
route-policy-name: Routing policy name, a string of 1 to 63 characters.
half-life-reachable, half-life-unreachable, reuse, suppress and ceiling are mutually dependent. Once
any one is configured, all the others should also be specified.
Description
Use dampening to enable IPv6 BGP route dampening, configure dampening parameters, or both.
