BGP Overview for AI-ML Data Centers

date_range 20-Dec-24
arrow_backward
arrow_forward

Learn the benefits of BGP for an AI-ML data center deployment.

BGP is an exterior gateway protocol (EGP) that routers in different autonomous systems (ASs) use to exchange routing information. BGP routing information includes the complete route to each destination. BGP uses the routing information to maintain a database of network reachability information, which it exchanges with other BGP systems. BGP uses the network reachability information to construct a graph of AS connectivity. This AS connectivity graph enables BGP to remove routing loops and enforce policy decisions at the AS level.

BGP enables policy-based routing (PBR). You can use routing policies to choose among multiple paths to a destination and to control the redistribution of routing information.

In AI-ML data center deployments, you can use BGP to effectively exchange equal-cost multipath (ECMP) link or load balancing-related control plane information between layers of the Clos network. The features described in this guide use this information to improve the performance of your AI-ML data center network.
