Worked on the LabNConsulting/frr repository to address a crash in pimd related to MSDP Source-Active (SA) message handling when peers are configured in a mesh-group. Used C and Python to implement a fix ensuring the forwarding logic correctly respects peer group membership, thereby improving the stability and reliability of multicast state advertisement forwarding. Developed and integrated a topotest to validate MSDP SA forwarding between a mesh-group peer and two additional peers, confirming correct bidirectional state propagation. This work demonstrated strong debugging skills, protocol development expertise, and a focus on robust network programming and automated testing within complex networking environments.
