Does anyone know if it is possible to enable Per-VRF BGP Dampening? I have a router running 12.4(9)T and when I enable BGP dampening within an address-family, it is enabled under all routing contexts and within VPNV4.
Any ideas?

Hello Jon,
try to give the command only under the address-family of interest
it should be supported
Command Modes
>>Address family configuration
Router configuration
see

Sorry, I haven't seen you had already done. This may be a bug in your release.
As a workaround you could try to use a route-map like in this example:
Router(config)# router bgp 50000
Router(config-router)# address-family ipv4
Router(config-router-af)# bgp dampening route-map BLUE
Router(config-router-af)# end
Hope to help

Hi Giuseppe,
Thanks for your reply. Under the address-family is where I entered it and yes it is supported. However, my question was that when I enter the command under the relevant address-family, it activates it for all address-families including the VPNv4 routing context.
I have tried this on a number of different IOS versions including the latest.
This would appear to be a feature in this case.

Hello Jon,
I would expect that if a command is given inside an af (address-family) its effect is limited to that af.
Otherwise, it would be wise to don't let available the command in address-family config mode but only in router-mode.
It is misleading.
Hope to help
