There are two main use cases for IPv6 in Abiquo: Automatic generation of IPv6 address and Manual entry of IPv6 address. When you create a network, if you set strict = true, the platform enforces EUI-64 IP address generation.
| Strict networks | Abiquo automatically generates IPv6 address |
|---|
| Description | - Abiquo can automatically generate the host-specific part of the IP to the EUI-64 standard
- Abiquo uses the MAC of the virtual machine to automatically generate the Host ID
- When the MAC is not yet available from the hypervisor (prior to deploy of public and external networks), Abiquo supplies a placeholder IP
- The placeholder IP:
- displays as a question mark "?"
- will be replaced with a real IP when the virtual machine is deployed
|
| Strict network? | Network parameter strict = true |
Router advertisement
system | - You must always configure the network in the router advertisement system for all IPv6 network types
- Unmanaged networks will usually receive their IPv6 addresses from the router advertisement system
- Public, external and private strict networks can also receive stateless IPv6 addresses from this system based on their MACs
- the DHCP server is not required, because Abiquo will generate and display the same IP addresses as the router advertisement system
|
| DHCPv6 | - In general, DHCPv6 is required to supply DNS information to the virtual machines
- DHCPv6 can be used to supply IPv6 addresses to the virtual machines
- The addresses generated by the router advertisement system from the MACs of the virtual machines should be the same as those generated by DHCPv6
- When a router advertisement system is used to assign the IPv6 address, the correct addresses should still be displayed in Abiquo
|
| Placeholder IPs | - EUI-64 requires the MAC from the hypervisor
- A placeholder IP is used until the MAC is provided by the hypervisor at deploy time
- The placeholder IP is represented by a "?"
|
| Non-strict networks | User may manually enter IPv6 address |
|---|
| Description | - You can manually enter an IPv6 address in Abiquo
- This address must be valid for the IPv6 network
- Cloud users can select from these IPv6 addresses when configuring their virtual machines
|
| Strict network? | Network parameter strict = false |
Router advertisement
system | - You must always configure the network in the router advertisement system for all IPv6 network types
|
| DHCPv6 | - DHCPv6 service is required to supply IPv6 addresses and DNS information to the virtual machines
- DHCPv6-ready templates are required:
- Windows: configure DUID in registry
- Unix: configure dhcpv6 client and firewall/security
- The DHCPv6 service can assign static addresses
- 1 x IPv6 address to a Windows virtual machine
- Multiple IPv6 addresses to a Unix virtual machine with appropriate template configuration
|
Automatic IPv6
generation
is also supported | - Abiquo can also automatically generate an IPv6 address for non-strict private, public and external networks
- If the MAC is available, generate an IPv6 address in EUI-64 format
- If the MAC is not available, (prior to deploy in external or public networks), generate a random IPv6 address
|
A basic sample configuration for testing the Manual IP entry use case is available from Abiquo Support.
