Developed multi-interface outbound support for static multicast routes in the PIM Daemon within the LabNConsulting/frr repository, enabling configuration of multiple outgoing interfaces per static mroute to enhance network scalability and control. The work involved updating the YANG model to represent multi-OIF capabilities, refining configuration processing logic, and implementing an automated test to validate the new functionality. Leveraging expertise in network routing, protocol implementation, and software development, the solution was delivered using C and Python. This feature allows for more granular management of multicast traffic, addressing the need for flexible and scalable routing in complex network environments without introducing regressions.
