For historical inheritance, the bond6 with ipv4 is widely used in our lab. We started to support ipv6 for all service last year, networking operation and maintenance team think it does work with ipv6 ALB capacity take it for granted due to bond6's specification but it doesn't work in the end. as you know, it is impossible to change link neworking to LACP because of huge cost and effective to online server.
