Can CFE support moving IP prefixes in AWS?

[mikeoleary]

Do you already have an issue opened with F5 support?

No.

Description

AWS recently announced the ability to configure an ENI with a range of IP address, as opposed to /32 address. There's a few limitations in the details, including that IPv4 prefixes must be /28 and IPv6 must be /80.

I have tested with CFE v1.9, where I had an A/S pair and the Active device was configured with IPv4 address, multiple IPv6 addresses, and an IPv4 range of /28. Upon failover, CFE worked as expected (IPv4 and IPv6 addresses failed over), but the IPv4 range did not fail over.

Could we see support for moving of IP prefixes in AWS in future? I have not had this as a requirement from a customer yet (I think the announcement of the feature was yesterday) but I expect that customers will find these prefixes a popular option.
