I came up with a solution for networks with ISP connections to deal quickly with DDOS attacks without having to be able to work with a network technician at the ISP for immediate relief. If the ISP agrees, install a second low speed connection to the same router your primary router BGP peers with. Through this low speed connection you run a second bgp session advertising the /32 that is being attacked by the DDOS. You mark the /32 as NO-ADVERTISE so the route doesn't leave the border router.

Or, without adding an extra connection, negotiate a NULLROUTE community with your upstream provider. This would be a wonderful addition to the well-known BGP communities. I'll bring this up on IDR. Mark
