      Yes.  We have enabled route-flap dampen on all BGP speakers now.
      
      Some more info, the 7000 in concern has 18 (11 EBGP & 7 IBGP) BGP sessions 
      running.  We have noticed slow down after migrating to 11.x but the added 
      functionality (route-flap dampening) worthed the upgrade.  We are 
      considering adding RSP7000, any comment.
      
      Cheers,
      
      William
