RustyBGP is my first attempt at routing protocol written in, you guessed it, Rust.

What is implemented:

• Processing of the following BGP messages: Open, Keepalive, Updates
• Neighborship comes up
• Keeping the neighborship up
• Sending routes
• Receiving routes
• IPv4 Unicast Address Family
• Async via Tokio
• 2 byte and 4 byte ASN
• Resuming of neighbors after they go down
• Optional parameters for neighbors (capabilities like AS4, and other address families)
• Receiving and understanding (but not doing anything with) Notifications

What isn't implemented yet:

• GUI
• Best Path Calc.
• Processing of BGP Notification
• Handling of route refresh
• Other address families
