Analyzing Load Balancer VIP Routing with Calico BGP and MetalLB https://www.ahdark.blog/analyzing-load-balancer-vip-routing/ MetalLB (controller-only) with Calico BGP does not bind VIPs to any node interface, causing ARP failures. Services stay unreachable externally. Solution: locally bind VIPs, enable strictARP, and disable rp_filter to restore correct traffic flow.
