Border Gateway Protocol (BGP) has traditionally been associated with hardware routers and static configurations, but modern networks increasingly demand software‑defined, programmable control planes. GoBGP, an open source BGP implementation written in Go, offers a rich API surface that enables dynamic policy changes, on‑the‑fly route injection, and tight integration with automation systems and controllers. This talk explores the practical challenges and solutions involved in turning GoBGP into a multi‑tenant, production‑grade BGP control plane. We will start with a brief overview of GoBGP's architecture and its gRPC/HTTP APIs, then dive into how those APIs can be leveraged to build a flexible control plane that reacts in real time to external events (for example, service discovery, telemetry feedback, or orchestration workflows).

The core of the session focuses on multi‑tenancy and operational aspects: - Building logical separation between tenants while sharing the same GoBGP control plane. - Mapping tenants to their own BGP server, route policies, and address families, and keeping configuration manageable as the number of tenants grows. - Handling dynamic tenant lifecycle events (creation, updates, deletion) through the API without disrupting existing sessions.
