Configuring VXLAN

Cisco Nexus 9000 switches are designed for hardware-based VXLAN function. It provides Layer 2 connectivity extension across the Layer 3 boundary and integrates between VXLAN and non-VXLAN infrastructures. This can enable virtualized and multitenant data center designs over a shared common physical infrastructure.

VXLAN provides a way to extend Layer 2 networks across Layer 3 infrastructure using MAC-in-UDP encapsulation and tunneling. VXLAN enables flexible workload placements using the Layer 2 extension. It can also be an approach to building a multitenant data center by decoupling tenant Layer 2 segments from the shared transport network.

When deployed as a VXLAN gateway, Cisco Nexus 9000 switches can connect VXLAN and classic VLAN segments to create a common forwarding domain so that tenant devices can reside in both environments.

This section contains payload examples and CLIs to demonstrate how to use the NX-API REST API to configure VXLAN BGP EVPN on Cisco Nexus 3000 and 9000 Series switches and to show how the REST APIs correspond to the CLI commands.
