Akashi worked on the LabNConsulting/frr repository, focusing on enhancing protocol correctness and interoperability in SRv6 with IPv6 Multi-Topology environments. Using C programming and network protocol development skills, Akashi addressed a nuanced bug involving the handling of MTID values in SRv6 locator TLVs. By updating the isisd component to ensure SRv6 locator TLVs use the correct IPv6 MTID, Akashi aligned their behavior with IPv6 reachability TLVs, thereby improving compatibility with other implementations. The work demonstrated careful attention to protocol standards and cross-system stability, delivering a targeted fix with clear traceability and minimal risk to the existing codebase.
