Howdy!
https://kube-vip.io does two things: - Control Plane HA w/BGP or ARP - Service Type: LoadBalancer w/BGP or ARP
It is similar to metallb but has a number of differences under the covers in how it works inside Kubernetes, it is cloud controller agnostic so as long as something attaches an IP to spec.IngressIP then kube-vip will advertise it. For edge deployments loadBalancers addresses can use the local DHCP for addresses etc..
