Introduction to BRKDCN-2980.pdf
This technical whitepaper serves as the authoritative configuration reference for implementing VXLAN EVPN architectures on Cisco Nexus 9000 Series switches, specifically targeting NX-OS 7.3(2)D1(1) environments. Published in Q3 2025, the document consolidates Cisco’s validated design patterns for building scalable data center fabrics with automated underlay provisioning and multi-tenant overlay segmentation.
The 298-page guide focuses on operational best practices for spine-leaf topologies using Nexus 93600CD-GX platforms, while maintaining backward compatibility with first-generation 40GbE QSFP modules. Network architects will find detailed workflow diagrams for integrating Nexus Dashboard Fabric Controller (NDFC) with third-party orchestration tools through REST API endpoints.

Compatibility and Requirements
| Supported Platforms | Minimum NX-OS | NDFC Version |
|---|---|---|
| Nexus 9336C-FX2 | 7.3(2)D1(1) | 12.1(1e) |
| Nexus 93600CD-GX | 7.3(3)D1(2) | 12.2(1a) |
| Nexus 9508 Mod Chassis | 7.3(1)D1(4) | 12.0(3q) |
Critical Notes:
- Requires Python 3.9+ runtime for automation scripts
- Incompatible with legacy OTV configurations from NX-OS 6.x releases
- May conflict with third-party SDN controllers using OpenFlow 1.3 protocol
