Is there a hard or practical limit on how many public/private IP addresses that are supported in CFE beyond the number of EIPs allowed by AWS

Do you already have an issue opened with F5 support?

No.

Description

We are getting a number of requests to configure virtual addresses on one of our HA Pairs in AWS. Is there a hard or practical limit on how many public/private IP addresses that are supported in CFE beyond the number of EIPs allowed by AWS?

Hi @pedley-f5, we've tested with up to 25 EIPs: https://clouddocs.f5.com/products/extensions/f5-cloud-failover/latest/userguide/performance-sizing.html#aws

Since these are updated asynchronously, I don't see any thing that would limit the number of EIPs you can update in one failover execution.
