CN-Series Hyperscale Security Fabric (HSF) introduces dynamic routing through BGP and BGP over BFD protocols. Using Dynamic routing, you can attain stable, high-performing, and highly available layer 3 routing through profile-based filtering lists and conditional route maps, which can be used across logical routers. These profiles provide finer granularity to filter routes for each dynamic routing protocol and improve route redistribution across multiple protocols.

BGP looks for the available paths that data could travel and picks the best route, based on IP prefixes that are available within autonomous systems. The Bidirectional Forwarding Detection (BFD) provides fast forwarding path failure detection times for BGP routing protocols between CN-GW pods and the external router.
