Redundancy / Self-ip

I have a pair of F5 BIG-IP 4.x Link Controllers; they are setup as Active/Standby. I have the need to break apart the redundancy so they can run independent of each other. The reason I am doing this so I can introduce a new F5 Link Controller 9.x, we cannot upgrade the existing LC to 9.x.

 

 

I keep getting stuck on how to do this in regards to the Self-IP / floating Self-IP,

 

 

example:

 

 

F5-LC-A

 

Interface 1, IP: 10.10.10.1, Floating Self-Ip: 10.10.10.20

 

Interface 2 , IP: 20.20.20.1, Floating Self-Ip: 20.20.20.20

 

 

F5-LC-B

 

Interface 1 , IP: 10.10.10.2, Floating Self-Ip: 10.10.10.20

 

Interface 2 , IP: 20.20.20.2, Floating Self-Ip: 20.20.20.20

 

 

I will need to retain the Self-IP address on F5-LC-A due to routing, source ip address security, etc.

 

I assume I can just make the Self-IP non-floating.

 

 

Also when I introduce the new LC to replace the existing F5-LC-B I will need to create Self-IPs for the Vlans.

 

 

If anybody has any thoughts would be great….Thanks ….
