Worked on the FRRouting/frr repository to enhance the stability and reliability of BGP neighbor route JSON outputs. Focused on resolving a bug that caused inconsistent JSON formatting across advertised, received, and filtered route types, the work involved implementing conditional JSON emission to maintain backward compatibility with existing automation tools. Using C and Python, applied skills in BGP, JSON handling, and network engineering to ensure that all route types produced valid, predictable JSON. This targeted fix reduced parsing errors for downstream automation and improved operator confidence in FRR’s interfaces, supporting more robust test automation and smoother integration with external tooling.
