Wajahat enhanced SONiC’s network automation capabilities by implementing comprehensive Multiple Spanning Tree Protocol (MSTP) support across the sonic-buildimage, sonic-swss, and sonic-utilities repositories. He introduced a new YANG model for Spanning Tree Protocol, enabling fine-grained PVST and MSTP configuration through Python and YANG modeling. In sonic-swss, he integrated MSTP logic into stpmgr using C++ and SAI APIs, supporting dynamic MST instance and port management. Additionally, he developed CLI and configuration database features in sonic-utilities, allowing users to manage MSTP settings at global, region, and interface levels. The work demonstrated strong depth in network protocols and configuration management.
