FTAS 2.3 Enhances SONiC Testing for Data Center Interconnections

November 15, 2025

Fabric Test Automation Suite (FTAS) has been updated to include features that enhance the assessment of SONiC deployment readiness. The new version integrates customer feedback and aligns with recent SONiC releases to improve testing accuracy and efficiency.

Data Center Interconnect

Data Center Interconnect (DCI) integrates various advanced technologies, such as EVPN, Virtual Extensible LAN (VXLAN), and MCLAG, to enhance network orchestration. These technologies collectively facilitate control plane operations, provide seamless virtual network extension, and ensure redundancy and load balancing, addressing the challenges associated with interconnected data centers.

BGP-EVPN with VXLAN

VXLAN EVPN extends Layer 2 connectivity across Layer 3 networks, improving management of virtualized workloads and enabling effective distribution of Monitoring-as-Code (MaC) and IP addresses. Its adaptable structure supports modern data center implementations, aiding in Network Virtualization (NV) and resource management.

MCLAG

MCLAG (Multi-Chassis Link Aggregation) improves data center reliability by enabling traffic rerouting to backup switches during failures. This contributes to high availability, balanced resource distribution, and streamlined network design, crucial for applications that demand uninterrupted connectivity.

ECMP Scaling & Resilience

ECMP (Equal-Cost Multipath) enhances network efficiency by managing traffic distribution across multiple equally-cost paths. This technique is valuable in data center environments for load balancing and ensuring redundancy, thereby facilitating continuous service delivery.

Summary

FTAS 2.3 introduces features that enhance SONiC evaluations, including new test cases for VXLAN EVPN and MCLAG scenarios, aimed at bolstering resilient data center networks. These updates support improving operational reliability and preventing downtime.

This blog signals a timely, fact-based summary of FTAS 2.3 and its implications for enhancing DCI quality.
