MetalLB with Calico BGP: Deployment, Architecture, and Validation
Deploy MetalLB as controller-only and let Calico’s BGP advertise a LoadBalancer pool. The guide covers Helm setup, IP pool config with avoidBuggyIPs, route flow analysis, source-IP-preserving Local policy, and failover tests for production-grade bare-metal LB.

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.
