HA Pair Across Availability Zones in AWS

Hola,

 

I'm in the process of testing out how to deploy a F5 HA pair across Availability Zones within AWS. We would have BIG-IP A in AZ1 and BIG-IP in AZ2. Has anyone had any success with this? I was able to spin two instances without any issue but trying to get them to sync configurations at this point is a bit troublesome.

 

VPC 10.5.0.0/16 Mgmt AZ1 Subnet 10.5.0.0/24 Ext AZ1 Subnet 10.5.1.0/24 Mgmt AZ2 Subnet 10.5.10.0/24 Ext AZ2 Subnet 10.5.11.0/24

 

BIG-IP A:

 

10.5.0.200 Management Address10.5.1.200Self-IP on External VLAN

 

BIG-IP B:

 

10.5.10.200Management Address10.5.11.200Self-IP on External VLAN

 

I was able to add the devices into a Device Group but the sync throws the following error:

 

Static route gateway 10.5.11.1 is not directly connected via an interface.
