Yes, you can assign multiple ip's to a single big-ip interface which you then use for another virtual server:443. Once the private ip has been configured on your big-ip interface you map another EIP addresses to the newly created big-ip secondary address.

 

Here is an alternative option for using a single vs with SNI feature:

Thanks for the reply.

 

I was stuck on where/how to assign the secondary IP address(es) to be used for the Virtual server(s) as the documentation is very light at that step. Here's the process:

 

  1. In EC2 console, under "Network Interfaces", find the external interface for the BigIP
  2. Right click and select "Manage IP Addresses"
  3. Assign new IP (10.0.1.202 in their example)
  4. Go to "Elastic IPs", Associate Address. Select the Network interface, and in the Private IP drop-down you'll see the secondary IP address
  5. On the BigIP, create a Virtual Server with IP address 10.0.1.202
  6. Modify security groups according to allowing whatever ports are used by the Virtual Server

Now, what I don't understand is how this would work with HA. It seems since the Virtual Server IPs are mapping to a specific instance, failover would not take place for Virtual Server IP addresses.
