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 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 select 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 and use US-East as a backup if US-West experiences any QoS issues.
For a list of commonly-used BGP Communities, see How do BGP communities work for customer routing preferences?
