Hi,
For a shared network with IPv6, you need to configure SLAAC on the upstream
router, as CloudStack VR is not the IPv6 gateway.
Correct with a few additions:
- Make sure you set the lifetime of the RA to something like 60s and the
interval to 10s, this makes for a fast failover
OR
- Use VRRPv3 and sent out SLAAC with the Unicast VRRPv3 address
- You might want to sent the rDNS servers with SLAAC as well
- Make sure privacy extensions are disabled inside the VMs

Hi All;
I am using Cloudstack 4.19, I am trying to enable IPv4+IPv6 Dual Stack
Networking for Shared Networks, so I add a new network with both dual stack
ip definitions in Shared Mode. I started the vm and I noticed that I don't
get ipv6 ip from VR.
I connected to VR to check dhcp server/dnsmasq setup and it's setup is ok
but I noticed that VR's eth0 does only have an ipv4 ip address not v6. I
started to investigate more in VR and I noticed that ipv6 is disabled by
sysctl settings so network setup could not be successfully applied. By the
way, I am using the 4.19 SystemVM template.
So it looks like the VR image does not like to work with IPv6, I started to
investigate Network Offerings to check out if ipv6 needs to be enabled for
shared networking somewhere but I could not find any specific settings.
Does anyone have any clue for the missing piece?
Thanks
Ozhan
