During a two-month period, Frank Kong enhanced the sonic-net/sonic-mgmt repository by improving test stability and advancing VXLAN BGP dualtor robustness. He addressed test flakiness by refining the Python-based test harness to ignore specific errors in duplicate routes, resulting in more reliable CI feedback. In March, Frank consolidated fixes for VXLAN BGP dualtor configurations, ensuring both ToRs in active-active deployments handled traffic correctly and reducing packet loss. His work involved Python scripting, network programming, and test automation, with careful attention to synchronization and topology awareness, ultimately strengthening test coverage and deployment confidence for complex dual-ToR network architectures.

Mar 1, 2026March 2026 — sonic-mgmt monthly summary. Key features delivered: - VXLAN BGP dualtor robustness and testing improvements: Consolidated fixes to VXLAN BGP dualtor configuration and testing; fixed test setup for VXLAN BGP subinterfaces (port mapping and ACL activation) and corrected VXLAN configuration for active-active dualtor to ensure both ToRs handle traffic and prevent packet loss. Commits: 80f5f80180c7abd379f5b7a024aeb0c4894c44e7 (#23021). - VXLAN decap for active-active dualtor (dualtor-aa): Applied VXLAN tunnel/map and switch config to both ToRs; ensured traffic hashed to both ToRs and maintained connectivity. Commits: 44103cc316e6b267f4d5e028db241ef494123d8d (#23015). Major bugs fixed: - Fixed test_vxlan_vnet_bgp_subintf setup KeyError in dualtor port mappings; added safe lookups and wait logic for ACL activation to stabilize test dynamics across platforms (Titan T0 / slower platforms). - Fixed test_vxlan_decap for dualtor-aa by applying configuration on both ToRs; resolved traffic drops when Topology hashed to the non-selected ToR. Overall impact and accomplishments: - Significantly increased reliability of dual-ToR VXLAN deployments, reducing packet loss and flaky CI tests, enabling faster validation and safer production rollouts. - Strengthened CI feedback loop and test coverage for multi-TO R topologies, improving deployment confidence in dual-toR architectures. Technologies/skills demonstrated: - VXLAN, BGP, dual ToR architectures, Python-based test harness, PT negotiation and topology awareness, CI/test automation, and advanced debugging of complex network topologies.
