April 2026 monthly summary for sonic-mgmt focused on expanding network scalability validation capabilities. Delivered BGP scalability test coverage across multiple VNets by adding dynamic BGP peers and per-vnet/subinterface configurations, enabling automated validation that BGP sessions are established per vnet. This work strengthens the test framework for large-scale deployments and reduces risk in production rollouts. Prepared for backport readiness to multiple release tracks (202506, 202511) to ensure ongoing coverage across supported platforms.

March 2026: VXLAN validation and scale-test enhancements in sonic-mgmt focused on improving reliability and correctness of overlay routing, with end-to-end verification and planning groundwork for scalable deployments across platforms.

December 2025: Focused on validating and stabilizing overlay networking features with a new VXLAN tunnel route scalability test suite, improved test reliability by gating tests on supported ASIC platforms, and enhanced configuration integrity through cleanup on reload. These efforts deliver measurable business value by strengthening validation coverage, reducing flaky test results, and preserving accurate state across reloads.

November 2025 monthly summary for sonic-net/sonic-mgmt focusing on T0 topology testing improvements and scalable VXLAN ECMP validation across endpoints. Highlights include dynamic BGP test configuration sourced from config_db to replace hardcoded neighbor data, a new scalable VXLAN ECMP testing framework, and validated reliability on physical T0 testbeds.

May 2025: Delivered dynamic BGP range management capabilities and expanded test validation across sonic-buildimage and sonic-mgmt, driving reliability and deployment confidence for dynamic routing configurations. Implemented end-to-end support for modifying IP ranges for dynamic BGP peers, including add/remove operations, overlap handling, persistence, and template-based management for dynamic listen ranges, complemented by robustness checks and unit tests. Developed and documented a comprehensive test plan for dynamic BGP peer IP range modifications in sonic-mgmt, including Per-Vnet BGP scenarios and dynamic peer modification, with templates, configurations, and tests to validate peer states, route learning, and IP range changes. The work strengthens operational efficiency and reduces risk for large-scale deployments by increasing automation, test coverage, and cross-repo alignment.

April 2025 — sonic-buildimage: Focused on enabling BGP Peer support inside VNETs and expanding test coverage. Delivered cross-VNET BGP peering by routing configurations through bgpcfgd, enabling persistent BGP configurations within VNETs and aligning with cloud-scale networking goals. The work included automated tests for IPv4 and IPv6 VNET environments and a gating change to remove a blocking check for BGP peers in VNETs.
