Worked on the LabNConsulting/frr repository to enhance the reliability of OSPF6 routing by addressing a specific bug in route type calculation. Focused on C programming and network programming, the developer updated the logic to ensure the default route is properly included when determining the maximum route type, which directly impacts route redistribution and configuration display accuracy. This targeted fix reduces the risk of misrouting in OSPF6 deployments and improves network stability. The work was carefully documented with a clear commit message, supporting future traceability and troubleshooting. Emphasis was placed on correctness, minimal risk, and clarity in routing protocol maintenance.
