MetalLB is a load-balancer implementation for bare metal Kubernetes clusters, using standard routing protocols, including BGP. In the past year, the native go based BGP implementation has been replaced by an integrated FRRouting instance running in a container. In this talk I am going to briefly introduce how MetalLB leverages BGP to implement Kubernetes services, describe the integration mechanism with FRR and how it made the MetalLB evolution faster and easier. I'll finally explain how the MetalLB CI works, and how we leveraged FRR to mimic various network topologies in order to extend number of scenarios we want to cover.
