The record

Purpose: OpenELB exposes Kubernetes LoadBalancer services for external access in bare-metal, edge and virtualization environments.
Load balancing modes: OpenELB supports load balancing in BGP mode and Layer 2 mode, and its documentation also describes VIP mode.
Routing: OpenELB supports ECMP routing and load balancing; its BGP mode uses GoBGP to publish service routes to peer routers.
IP address pools: Eip objects provide address pools from which OpenELB assigns IP addresses to Kubernetes LoadBalancer services.
Address family limit: The documentation says OpenELB currently supports only IPv4.
Installation: OpenELB can be installed in a Kubernetes cluster using kubectl manifests or Helm 3.
Kubernetes requirement: Installation requires Kubernetes 1.15 or later because OpenELB requires CustomResourceDefinition v1.
Layer 2 prerequisites: Layer 2 mode requires the infrastructure to allow anonymous ARP/NDP packets.
Layer 2 limitations: Layer 2 mode forwards traffic through one active node, so failover briefly interrupts services and bandwidth is limited to that node.
BGP prerequisites: BGP mode requires a router that supports BGP and ECMP; the documentation recommends it for high availability without failover interruptions or bandwidth bottlenecks.
Integrations: The project lists installation guides for Kubernetes, K3s and KubeSphere.
Support: The project directs users to the KubeSphere Slack channel for support and discussion.
License: OpenELB is licensed under Apache License 2.0.
Project status: The repository says OpenELB was originally created by KubeSphere and is a vendor-neutral CNCF Sandbox Project.
