During April 2026, Wangdan contributed to the FRRouting/frr repository by enhancing BGP confederation stability and efficiency. Focusing on the BGP protocol, Wangdan modified the bgpd codebase in C to prevent unnecessary BGP peer resets when confederation configuration remained unchanged, addressing a subtle but impactful bug. The solution involved moving validation logic to ensure resets only occurred when confederation IDs actually changed, thereby reducing session churn. Wangdan also expanded automated test coverage using Python and the topotest framework, verifying stability during confederation ID changes or deletions. This work demonstrated careful attention to protocol correctness and robust network programming practices.
