Overview¶
The purpose of this document is to guide the user in deploying 6WIND HNA in a BGP EVPN use-case.
In this scenario, the HNA, running as a Kubernetes pod, will extend the Network Fabric up to Kubernetes nodes, and will provide a network connectivity to CNF containers with good performance and flexibility, avoiding the use of SR-IOV.
Overview of the HNA EVPN Scenario.¶
This deployment guide shows how to connect at Ethernet level and isolate each CNF of a specific tenant. This is implemented by a simple Ethernet bridge for traffic that is local to a Kubernetes node, or through a VXLAN tunnel for inter-nodes traffic.
Example of network traffic in the HNA EVPN Scenario.¶
The network connection between the HNA and the CNF is either a
veth
interface (for CNF Pods running on Linux) or a virtio-user
if the CNF supports it (Virtual Service Router for instance).
