Can anyone relate any information with regards to how Juniper routers differ from Cisco in respect to BGP dampening? We are seeing issues with one of our peers who is using an M20. If the BGP session is cycled, that peer is damping our routes for aprox 1hr. We don't have this problem with any other peers, all of whom are using Cisco products. There has to be some huge difference in the way that the Juniper is calculating the penalty and decay. Any help is greatly appreciated. --- John Fraizer EnterZone, Inc

there once was a bug where junos penalized flaps twice, once at withdraw time and once at re-advertize time. you can compensate by doubling your/the default params.

Any help is greatly appreciated.
