Route Flap Dampening
--------------------
-.. clicmd:: bgp dampening [(1-45) [(1-20000) (1-20000) (1-255)]]
+.. clicmd:: bgp dampening (1-45) (1-20000) (1-20000) (1-255)
- This command enables (with optionally specified dampening parameters) or
- disables route-flap dampening for all routes of a BGP instance.
-
-.. clicmd:: neighbor PEER dampening [(1-45) [(1-20000) (1-20000) (1-255)]]
-
- This command enables (with optionally specified dampening parameters) or
- disables route-flap dampening for all routes learned from a BGP peer.
-
-.. clicmd:: neighbor GROUP dampening [(1-45) [(1-20000) (1-20000) (1-255)]]
-
- This command enables (with optionally specified dampening parameters) or
- disables route-flap dampening for all routes learned from peers of a peer
- group.
+ This command enables BGP route-flap dampening and specifies dampening parameters.
half-life
- Half-life time for the penalty in minutes (default value: 15).
+ Half-life time for the penalty
reuse-threshold
- Value to start reusing a route (default value: 750).
+ Value to start reusing a route
suppress-threshold
- Value to start suppressing a route (default value: 2000).
+ Value to start suppressing a route
max-suppress
- Maximum duration to suppress a stable route in minutes (default value:
- 60).
+ Maximum duration to suppress a stable route
The route-flap damping algorithm is compatible with :rfc:`2439`. The use of
- these commands is not recommended nowadays.
+ this command is not recommended nowadays.
At the moment, route-flap dampening is not working per VRF and is working only
for IPv4 unicast and multicast.
- With different parameter sets configurable for BGP instances, peer groups and
- peers, the active dampening profile for a route is chosen on the fly,
- allowing for various changes in configuration (i.e. peer group memberships)
- during runtime. The parameter sets are taking precedence in the following
- order:
-
- 1. Peer
- 2. Peer group
- 3. BGP instance
-
- The negating commands do not allow to exclude a peer/peer group from a peer
- group/BGP instances configuration.
