This section has generated quite a lot of discussions on e-mails and on slack. First it creates the doubt that MetalLB is incompatible with IPI deployments as IPI uses the same underlying mechanisms as IP Failover (VRRP and keepalived). Second, talking to MetalLB engineering, they are not aware of any incompatibility (at least not with the L3 mode). I think this is more like we expect people to use MetalLB instead of IP failover and not a real incompatibility.
