BGP

The bgp crate is an implementation of the Border Gateway Protocol, which is used to exchange routing and control plane information between Autonomous Systems.

The aim of this project is to provide a modern, high performance, secure, programmatic and customizable software package that can be useful to network operators, researchers, and people interested in Internet.

Current status.

The project is currently being rewritten from scratch to be more modular and maintainable, as well as to fix deeper issues with the previous implementation.

⚠️ Warning: This is currently a work in progress and not ready for use.

🛣️ Roadmap to v1.0

We aim for the 1.0 release to be functional and stable to operate peering sessions, and to install routes in the Linux Kernel.

• ☐ Implement basic parsers for the fundamental types required
  • ✅ Path Attributes from RFC4271
  • ✅ Open message
    • ✅ Capabilities from RFC4271
  • ✅ Update message
  • ☐ Notification message
• ✅ Implement scaffolding required to start and configure a server
• ✅ Implement connection logic to establish sessions with peers (passive and active)
• ✅ Routes originated from the configuration, with communities, announced to all peers
• ✅ Read-only HTTP API, status page and Prometheus metrics
• ☐ Implement an efficient data structure for storing prefixes (e.g. Poptrie)
• ☐ Filtering for peer RIB in / out
• ☐ Main / auxiliary RIBs for exchanging routes between peers

Development

CI runs these three on every push, and fails on any warning:

cargo fmt --all -- --check
cargo clippy --workspace --all-targets -- -D warnings
cargo test --workspace

Lints are configured once, under [workspace.lints] in the root Cargo.toml. unsafe code is forbidden throughout.
