I'm considering adding a keepalived load balancer to our infrastructure but I have some requirements which seem to be outside the normal configuration.
All our servers have public IP addresses, both IPv4 and IPv6. Some servers only have IPv4 addresses and I can use those behind keepalived and with arp_ignore.
IPv6 doesn't use ARP and I have not been able to find what, if anything needs to be done to support direct routing with IPv6 addresses (or if it is even possible with keepalived).
Anyone have experience with keepalived + IPv6 + Direct routing?
