Select your answer:

Show answer and explanation

Answer: CiliumLoadBalancerIPPool

Explanation

LB IPAM assigns external IPs to LoadBalancer Services from the CiliumLoadBalancerIPPool resources you create, and a pool can be limited to certain Services with a serviceSelector. Assigning an IP doesn't make it reachable. Cilium announces it with the BGP control plane or with L2 announcements over ARP and NDP.
