OVH IPv6 split between two servers?
Has anyone got OVH IPv6 to work between servers?
Example server 1 has IPv6 block 2001:db8:abcd:0012::0/64 allocated how could I use that same block on another server.
I saw the following response when someone asked about IPv6 through vRACK
vRack is a plain l2 network, so nothing special to get IPv6 to work. You however don't have a publicly routable range given to you, so 2 choices for IP addressing: either autconfiguration or use you own addressing in private ULA (fd00::/8)

Why do you want to use the same IPv6 subnet on both servers? Can be done, but one will have to route to/from the Internet via another. So why the overhead and complexity, doesn't the second server have its own separate subnet from OVH?
You tunnel the IPv6 through the vps which its allocated to and forward it to the other vps.
However, this increases your single point of failure.
Because I regularly upgrade my OVH server every 6-12 months when they offer new hardware. I do not want to have to mess around with configuring IPv6 when I do that.
Ideally I would just use my storage IPv6 block for everything related to IPv6.
Why don't you throw a load balancer in front?
How would I go about doing this what do you guys suggest?
The two servers would have IP blocks
2001:41d0:802:1be1::/56
2001:41d0:802:2be1::/56
All of the /56 needs to be able to work on both servers at the same time.
IPv6 don't have failover option with OVH as they are pointed to specific hardware.

Have you ever heard of DNS? Why do you guys even indulge such questions...
Cattle not pets. v6 is this paradigm taken to the extreme.
If you're attempting v6 permanence, you're doing something very, very wrong.
