Version 12.0 supports the final HTTP2 spec. 11.6.0 suports draft 14.

 

Because of the intertwining of http2 with SSL, it's unfortunately not as simple as merely dropping a http2 profile on the VIP. It has to be SSL-enabled, and needs to prefer certain ciphers that the http2 spec wants so that handshakes can complete successfully.

 

I know that you need at least this cipher string "ECDHE+AES-GCM:DEFAULT", but I haven't spent much time to test all the configuration options needed.

 

Hopefully this puts you in the right direction and someone else could add on it.
