F5® BIG-IP®: Active-Standby Cluster¶
Overview¶
The active-standby cluster template configures two (2) BIG-IP® devices to function as an ‘active-standby pair’ in a ‘sync-failover device group’. An active-standby pair is a pair of BIG-IP® devices configured so that one device is actively processing traffic while the other device remains ready to take over if failover occurs. A sync-failover device group contains devices that synchronize their configuration data and fail over to one another if a device becomes unavailable.
Prerequisites¶
- Basic understanding of BIG-IP® device service clustering.
- F5 OpenStack Heat Plugins installed on the Neutron controller.
- Three (3) VLANs configured in Neutron – ‘mgmt’, ‘control’, and ‘data’ – to be used for system management, high availability, and data traffic, respectively.
- Two (2) licensed, operational BIG-IP® devices (hardware or Virtual Edition); both must be connected to the ‘control’ VLAN.
- Login credentials for user(s) with administrative permissions on BIG-IP® device(s).

Caveats¶
None.
Deployment¶
- In Horizon, go to Orchestration –> Stacks.
- Click Launch Stack.
- Choose the Template File from its location on your machine, then click Next.
- Provide the information required for the Heat engine to build your stack. You can use the table below as a worksheet to gather all of the necessary information ahead of time.
- Click Launch. The Heat engine then creates your stack; the status changes to Create complete when it is finished.
| Configuration Item | Type | Entry/Description |
|---|---|---|
| Stack Name | string | Provide a name for the stack to be created |
| Creation Timeout | integer | Length of time after which stack creation will time out (minutes) |
| Password for user “<username>” | string | Enter the password for your user account |
| Cluster Name | string | the name you’d like to assign to the new cluster |
| FIP for first device | string | Floating IP address of the first BIG-IP |
| FIP for second device | string | Floating IP address of the second BIG-IP |
| Username for first device | string | the username of an admin user for the first BIG-IP |
| Password for first device | string | the admin user’s password for the first BIG-IP |
| Username for second device | string | the username of an admin user for the second BIG-IP |
| Password for second device | string | the admin user’s password for the second BIG-IP |
