Configuring BGP Peer Flap Dampening

To configure BGP Peer Dampening:

1. Navigate to the Global Configuration mode.
   

   SLX #configure terminal
   SLX (config) # 

2. Navigate to the router bgp context.
   

   SLX (config)# router bgp 
   SLX (config-bgp-router)#

3. Perform one of the following configurations:

   • Configure the global BGP peer dampening parameters

     

     SLX (config-bgp-router)# peer-dampening delay-hold 10 penalty 300 max-penalty 3600 stability-interval 1800
     SLX (config-bgp-router)#

   • Configure the BGP peer dampening configuration for a single neighbor.

     

     SLX (config-bgp-router)# neighbor 10.9.9.10 peer-dampening delay-hold 10 penalty 300 max-penalty 3600 stability-interval 1800
     SLX (config-bgp-router)#

   • Configure the BGP peer dampening configuration for a pre-defined peer group. In this example, the peer group name is 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)#

4. Exit out of the router bgp context.
   

   SLX (config-bgp-router)# exit
   SLX (config)# exit
   SLX# 

The following example consolidates the commands shown above to configure global BGP peer dampening:

SLX# configure terminal
SLX (config)# router bgp
SLX (config-bgp-router)# peer-dampening delay-hold 10 penalty 300 max-penalty 3600 stability-interval 1800
SLX (config-bgp-router)# exit
SLX (config)# exit
SLX#
