BIG-IP High Availability with Azure Route Server
Employee
EmployeeHello Nikoolayy1 , so nice to hear from you.
In my experience, most Azure customers use Azure LB or CFE. But if you do choose to use BGP, that's an option like you said. Personally, I didn't see the article you are talking about before it went away, but in Azure, I don't like to use a Floating IP (because to move that IP requires CFE).
I don't think a customer should configure iBGP between the BIG-IP devices unless they are intending an Active/Active setup, but in this article I walked through iBGP between devices. I think if it was Active/Standby, I would just set up eBPG between the BIG-IP devices and Azure.
I'm very open to feedback on this article. I've only done it a few times, because most customers end up using Azure LB.
MVPI am not working on Azure I am just using this as a basis for the config MichaelOLeary . I commented under
BIG-IP BGP Routing Protocol Configuration And Use Cases | DevCentral that you gave as a link.
My idea is if I need to configure iBGP between the F5 devices themselves to advertise the Floating ip as next hop from the two devices at the same time as only one of the two F5 devices will answer on that IP on layer 2 or just one BIG-IP will do the advertisement for the floating IP ?

I think it would be best not to use iBGP between F5 devices if you are in Active/Standby state and have a floating IP. For exactly the reason you mention.
