Table 508 damping command
Description This command configures the BGP connect retry timer value in seconds.
When this timer expires, BGP tries to reconnect to the configured peer. This configuration
parameter can be set at three levels: global level (applies to all peers), peer-group level
(applies to all peers in group) or neighbor level (only applies to specified peer). The most
specific value is used.
The no form of the command used at the global level reverts to the default value.
The no form of the command used at the group level reverts to the value defined at the global
level.
The no form of the command used at the neighbor level reverts to the value defined at the
group level.
Default 120 seconds
Parameters seconds — The BGP Connect Retry timer value in seconds, expressed as a decimal integer.
Values: 1 — 65535

Description This command enables BGP route damping for learned routes which are defined within the
route policy. Use damping to reduce the number of update messages sent between BGP
peers and reduce the load on peers without affecting the route convergence time for stable
routes. Damping parameters are set via route policy definition.
The no form of the command used at the global level disables route damping.
The no form of the command used at the group level reverts to the value defined at the global
level.
The no form of the command used at the neighbor level reverts to the value defined at the
group level.
When damping is enabled and the route policy does not specify a damping profile, the default
damping profile is used. This profile is always present and consists of the following
parameters:
Half-life: 15 minutes
Max-suppress: 60 minutes
Suppress-threshold: 3000
Reuse-threshold 750
Default no damping
