Hi Wido,

We do not allocate an ipv6 subnet to a VPC. Instead, we allocate an ipv6
subnet for each vpc tier.
These subnets have the same gateway (ipv6 addr in VR).

for example

ipv6 route fd23:313a:2f53:3111::/64 fd23:313a:2f53:3000:1c00:baff:fe00:4
ipv6 route fd23:313a:2f53:3112::/64 fd23:313a:2f53:3000:1c00:baff:fe00:4
ipv6 route fd23:313a:2f53:3113::/64 fd23:313a:2f53:3000:1c00:baff:fe00:4
