Select the desired region from the **Region** list.\n\n    1. If you chose to deploy your Active-Active database to an existing [Bring your own Cloud](https://redis.io/docs/latest/operate/rc/subscriptions/bring-your-own-cloud) account, you can define the VPC ID for the new region. Select **In existing VPC** and the set the VPC ID for the region.\n\n    1. Enter a unique CIDR address for the region.  \n    \n        Every CIDR should be unique to properly route network traffic between each Active-Active database instance and your consumer VPCs. The CIDR block regions should _not_ overlap between the Redis server and your app consumer VPCs. In addition, CIDR blocks should not overlap between cluster instances. \n\nWhen all **Deployment CIDR** regions display a green checkmark, you're ready to continue.  \n\n![Green checkmarks indicate valid CIDR address values.](https://redis.io/docs/latest/images/rc/icon-cidr-address-ok.png)\n\nRed exclamation marks indicate error conditions; the tooltip provides additional details.\n\n![Red exclamation points indicate CIDR address problems.](https://redis.io/docs/latest/images/rc/icon-cidr-address-error.png)\n\n    Select **Continue**.\n\n1. In the **Throughput** step, enter the desired read and write throughput for the new region.\n\n    You can also select **Set throughput as existing region** to duplicate the throughput settings from an existing region.\n\n    ![The Throughput step.](https://redis.io/docs/latest/images/rc/subscription-add-region-throughput.png)\n\n1.

Select **Continue** to add the region to your Active-Active deployment.\n\nRedis Cloud will provision the new region in the background and add it to all databases in the subscription. You aren't allowed to make changes to the database settings while this process is running. \n\nYour database will still be available, but you may notice some increased latency. This process will take some time depending on the size of your database."
