How to setup this in Azure CFE Prerequisites

1:- Virtual addresses created in a floating traffic group and matching addresses (secondary) on the IP configurations of the instance NICs serving application traffic
2:- We have single NIC in our existing F5 VMs, So can you please explain bit more step by step how to configure CFE in existing running BIG IP F5

Hi @vinod1190, the documentation here should have everything you need: https://clouddocs.f5.com/products/extensions/f5-cloud-failover/latest/userguide/azure.html

If there are specific questions about configuration, let us know.

Yes I follow the same link and did the setup in our azure subscription but I can see still standalone in Device Management-->Device. Could you help me how can we check or you need any output I will share.

That is not really related to CFE, it is a pre-requisite. You can follow the steps here to set up a cluster: https://techdocs.f5.com/en-us/bigip-14-1-0/big-ip-device-service-clustering-administration-14-1-0/creating-an-active-standby-configuration-using-the-setup-utility.html#GUID-2B766F81-3F76-4C42-9A5C-C60BF590ADC5
