Description
To minimize service degradation for customers using Routed DDoS protection, Silverline will engineer internal traffic routing between Scrubbing Centers for a CIDR prefix length that is less than or equal to /28.
-
In the examples illustrated below [Diagram One and Two], the customer would like to de-prefer US-East and prefer US-West due to a variety of reasons (better performance, faster route propagation, shorter BGP path to its own customers, etc.)
-
Customer can then select to advertise the route using a BGP Community string to send traffic through US-West instead. The second example [Diagram Three] indicates a traffic flow configuration that includes 3 distinct Scrubbing Centers.
For a list of commonly-used BGP Communities, see How do BGP communities work for customer routing preferences?
