Downgrading from 7.1.0.3 to 6.x is not supported due to incompatible VXLAN database schema.
| Version | Key Addition | Why Stick with 7.1.0.3? | |---------|--------------|--------------------------| | 7.0.3 | Basic VXLAN | Less stable EVPN. | | | Mature EVPN + vPC stability | "Goldilocks" release: stable but not yet heavy on resources. | | 7.2.0 | Segment Routing | Requires more CPU and memory. | | 8.0.1 | NX-API REST v2 | Heavier VM footprint. | cisco nxos titanium 7.1.0.3
: Supports exploration of VXLAN EVPN and Segment Routing (SR-MPLS) , providing a cost-effective way to learn these complex technologies. Use Cases and Simulation Environments Downgrading from 7
Ensure feature bgp and feature nv overlay are enabled. Verify loopback addresses are reachable. | | | Mature EVPN + vPC stability
: One of the primary advantages of simulating the Nexus 7000 series is testing VDC technology, which allows a single physical (or virtual) switch to be partitioned into multiple logical devices.
