Worked on the cprabha/featureprofiles repository to address compatibility issues in ISIS interface configuration, specifically targeting devices that do not support explicit AFI/SAFI enablement. Introduced a deviation-based conditional disablement within the configuration and test logic, allowing the system to adapt dynamically to device capabilities and reducing the risk of misconfiguration. This targeted bug fix, implemented in Go and leveraging protocol configuration skills, improved network interoperability and streamlined deployments across heterogeneous environments. The solution focused on minimizing changes while ensuring robust validation, ultimately decreasing post-deployment support needs and supporting smoother customer rollouts through enhanced network testing and configuration management.
