Parameters
-
peer-group
- The name of the peer-group to which this configuration must be applied to.
-
delay-hold
0-65535
- The amount of time, in
seconds, that a session remains in the idle-state after
the first peer flap event is received. During this time, all route
advertisements from this peer are ignored. The default value is zero (0)
seconds.
-
penalty
1-65535
- The amount of time, in
seconds, which gets added to idle-hold timer
every time a peer flap event is received. The default value is 300 seconds.
-
max-penalty
1-65535
- The maximum amount of time,
in seconds, that a session remains in the idle- state after
it has experienced repeated instability. The default value is 3600 seconds.
-
stability-interval
0-65535
- The interval of time, in
seconds, the session must be error-free in order to consider it to be
stable. The default value is 1800 seconds.
Usage Guidelines
-
BGP peer dampening can be global or on individual neighbor/peer-group.
-
All routes from a dampened peer will be removed from the routing table
-
When route dampening is also configured, peer dampening will take precedence
over route dampening.
-
Dampening cannot be applied to dynamic peers.
-
Dampening cannot be applied to administratively down neighbors.
-
When downgrading to a firmware that does not support peer-dampening, an
error will be displayed. You must remove this configuration to successfully
complete the downgrade.
Examples
The following example shows how to enable Peer Dampening for
a peer-group.
SLX (config)# router bgp
SLX (config-bgp-router)# neighbor 50.0.0.1 peer-group pg-level-1
SLX (config-bgp-router)# neighbor pg-level-1 peer-dampening delay-hold 10 penalty 300 max-penalty 3600 stability-interval 1800
SLX (config-bgp-router)#
