</div>

we’re implementing full-proxy HTTP2 on the BigIP 17.1.1 version of LTM and going thru the docs it appears implementing HTTP2 requires configuring SSL profile.

Could someone pls point me to the full-proxy HTTP2 configuration urls or docs?

Thanks.

Configuring HTTP/2 Full-proxy Support on the BIG-IP System

Overview: HTTP/2 full-proxy configuration

When your application server infrastructure is composed of HTTP/2-enabled servers, you can take advantage of the HTTP/2 acceleration features that the BIG-IP system provides. Most importantly, the BIG-IP system includes full-proxy support for the HTTP/2 protocol. This means that the BIG-IP system can process HTTP/2 requests and responses on both the client and server sides of the BIG-IP system.

The HTTP/2 full-proxy architecture provides greater network efficiency by allowing the BIG-IP system to transport multiple simultaneous, bi-directional streams of messages between the client and server. This is accomplished through the use of the BIG-IP system’s message-routing proxy, instead of the traditional connection-oriented TCP proxy.

This figure shows an example of the Acceleration area of the New Virtual Server screen, where you configure some key settings for successful HTTP/2 full-proxy operation.

HTTP/2 full-proxy configuration summary

To configure HTTP/2 full-proxy support on the BIG-IP system, you can use the BIG-IP Configuration utility.

When you create the virtual server, make sure that you select the

HTTP MRF Router

option. You will also assign two existing SSL profiles to the virtual server,

clientssl-secure

and

serverssl-secure

.

This illustration shows the tasks required to deploy an HTTP/2 full-proxy configuration.

Configuration constraints

These BIG-IP features are not supported for an HTTP/2 full-proxy deployment:

OneConnectThe session persistence types Hash and SSL.Connection mirroring in high-availability configurations.The Virtual Desktop Infrastructure (VDI) is not supported in HTTP/2 environment. Do not attach both HTTP/2 profile and VDI profile together in the virtual server.

The HTTP/2 protocol is not compatible with NTLM protocols.

Create a custom HTTP profile for HTTP/2 full-proxy configuration

Part of configuring an HTTP/2 full-proxy configuration on the BIG-IP system is to first create a standard HTTP profile. An HTTP profile defines the way that you want the BIG-IP system to manage HTTP traffic.

For the most expedient HTTP/2 full-proxy configuration, you can create a single HTTP profile that the BIG-IP system will apply to both client-side and server-side HTTP traffic. Alternatively, if you want the BIG-IP system to manage client-side and server-side traffic in different ways, you can create two separate HTTP profiles and configure the settings differently in each profile.

On the Main tab, click

Local Traffic

Profiles

Services

HTTP

.

The HTTP profile list screen opens.

Click

Create

.

The New HTTP Profile screen opens.

Type a unique

Name

for the profile.

From the

Parent Profile

list, select

http

.

Select the

Custom

check box.

From the

Request Chunking

list:

Select

Rechunk

if you always want the BIG-IP system to send a request to the server as chunked.Select

Sustain

if you want the BIG-IP system to decide whether to send a request to the server as chunked or unchunked.

From the

Response Chunking

list:

Select

Unchunk

if you always want the BIG-IP system to send a response to the client as unchunked. Note that if the content length is undefined because an HTTP payload handler modified the content, the system closes the connection.Select

Rechunk

if you always want the BIG-IP system to send a response to the client as chunked.Select

Sustain

if you want the BIG-IP system to decide whether to send a response to the client as chunked or unchunked.

Modify the other settings as required for your configuration.

If you want the BIG-IP system to manage server-side traffic differently from client-side traffic, click

Repeat

and create another HTTP profile.

Click

Finished

.

Any custom HTTP profile that you have created now appears on the HTTP profile list screen and is ready for you to assign to a virtual server.

Create a custom HTTP/2 profile

Part of creating an HTTP/2 full-proxy configuration is to create an HTTP/2 profile that you can use for both client-side and server-side application traffic. When you assign the profile to a virtual server, the BIG-IP system applies the settings in the profile to the traffic.

For the most expedient HTTP/2 full-proxy configuration, you can create a single HTTP/2 profile that the BIG-IP system will apply to both client-side and server-side HTTP/2 traffic. Alternatively, if you want the BIG-IP system to manage client-side and server-side traffic in different ways, you can create two separate HTTP/2 profiles and configure the settings differently in each profile.

On the Main tab, click

Local Traffic

Profiles

Services

HTTP/2

.

Click

Create

.

Type a

Name

for the profile, such as

my\_http2\_profile

.

For the

Parent Profile

setting, retain the default value

http2

, or select a different profile.

This setting specifies the profile that you want to use as the parent profile. Your new profile inherits all settings and values from the parent profile that you select.

From the

Settings

list, you can select

Advanced

to view the advanced settings.

This setting is optional, depending on the settings you want to configure.

On the far-right side of the screen, select the

Custom

check box.

In the

Concurrent Streams Per Connection

field, retain or change the numeric value.

This setting specifies how many concurrent requests are allowed to be outstanding on a single HTTP/2 connection.

In the

Connection Idle Timeout

field, retain or change the numeric value.

This setting specifies the number of seconds that a connection is idle before the connection is eligible for deletion.

From the

Insert Header

list, retain the default value of

Disabled

, or select

Enabled

.

This setting specifies whether the BIG-IP system should add an HTTP header to the HTTP request to show that the request was received over HTTP/2.

In the

Insert Header Name

field, retain the default value or, if the

Insert Header

setting is enabled, change the header name.

This setting specifies the name of the header that the BIG-IP system will add to the HTTP request when the

Insert Header

is enabled.

From the

Enforce TLS Requirements

list, ensure that

Enabled

. is selected.

Enforcing TLS requirements is required for successful HTTP/2 full-proxy deployment.

Forthe

Activation Modes

setting, retain the default value of

ALPN

(Application Layer Protocol Negotiation) or select

Always

.

This setting specifies the condition that will cause the BIG-IP system to handle an incoming connection as an HTTP/2 connection.

In the

Frame Size

field, retain the default value of

2048

, or change the value.

This setting specifies the size, in bytes, of the data frames that HTTP/2 will produce.

In the

Receive Window

field, retain the default numeric value of

32

, or change the numeric value.

This setting specifies, in kilobytes, the size of the receive window for HTTP/2 flow-control.

In the

Write Size

field, retain the default numeric value of

16384

, or change the numeric value.

This setting specifies the size, in bytes, of the SSL records that HTTP/2 will produce.

In the

Header Table Size

field, retain the default numeric value of

4096

, or change the numeric value.

This setting specifies the table size that the BIG-IP system will use for the compression of headers (unused).

If you want the BIG-IP system to manage server-side traffic differently from client-side traffic, click

Repeat

and create another HTTP/2 profile.

Click

Finished

.

Any custom HTTP/2 profile that you have created now appears on the HTTP/2 profile list screen and is ready for you to assign to a virtual server.

Create a basic server pool to process HTTP/2 traffic

You can create a pool of application servers enabled for processing HTTP/2 traffic. After creating the server pool, you must assign the pool to a virtual server.

Each pool member should be an HTTP/2-capable web server.

On the Main tab, click

Local Traffic

Pools

.

The Pools list screen opens.

Click

Create

.

The New Pool screen opens.

In the

Name

field, type a name for the pool.

Names must begin with a letter, and can contain only letters, numbers, and the underscore (\_) character.The pool name is limited to 63 characters.

Type a

Description

field, type a description of the pool.

For the

Health Monitors

setting, from the

Available

box, select a health monitor and move it to the

Active

box.

There are no HTTP/2-specific health monitors available on the BIG-IP system.

In the Resources area of the screen, from the

In the

Service Port

field, type a port number, or select a service name from the list.

If you enabled priority group activation, then in the

Priority

field, type a priority number.

Click

Add

.

Click

Finished

.

Create a virtual server to manage HTTP/2 traffic

You must create a virtual server to listen for HTTP/2 traffic, apply profiles and policies, and send the traffic to a pool of application servers that are HTTP/2-enabled.

Do not use the HTTP/2 protocol with NTLM protocols, as they are incompatible.

The BIG-IP does not support Virtual Desktop Infrastructure (VDI) in HTTP/2 environment. Do not attach both HTTP/2 profile and VDI profile together in the virtual server, a virtual server configured with both HTTP/2 profile and VDI profile can result in

ERR\_HTTP2\_PROTOCOL\_ERROR

.

On the Main tab, click

Local Traffic

Virtual Servers

.

The Virtual Server List screen opens.

Click

Create

.

The New Virtual Server screen opens.

In the

Name

field, type a unique name for the virtual server.

For the

Destination Address/Mask

setting, confirm that the

Host

button is selected, and type the IP address in CIDR format.

The supported format is address/prefix, where the prefix length is in bits. For example, an IPv4 address/prefix is

10.0.0.1

or

10.0.0.0/24

, and an IPv6 address/prefix is

ffe1::0020/64

or

2001:ed8:77b5:2:10:10:100:42/64

. When you use an IPv4 address without specifying a prefix, the BIG-IP system automatically uses a

/32

prefix.The IP address you type must be available and not in the loopback network.

In the

Service Port

field, type

443

or select

HTTPS

from the list.

From the

HTTP Profile (Client)

list, select a previously-created HTTP profile.

From the

HTTP Profile (Server)

list, select

(Use Client Profile)

.

Alternatively, if you created a separate HTTP profile for managing server-side traffic, select the profile from the list.

For the

SSL Profile (Client)

setting, from the

Available

list, select

clientssl-secure

, and move it to the

Selected

list.

This profile disables mid-stream SSL renegotiation by default. Disabling SSL renegotiation is a requirement for an HTTP/2 full-proxy deployment.

For the

SSL Profile (Server)

setting, from the

Available

list, select

serverssl-secure

, and move the profile to the

Selected

list.

This profile disables mid-stream SSL renegotiation by default. Disabling SSL renegotiation is a requirement for an HTTP/2 full-proxy deployment.

From the

Acceleration

list, select

Advanced

.

From the

HTTP/2 Profile (Client)

list, select the HTTP/2 profile that you previously created.

From the

HTTP/2 Profile (Server)

list, select

(Use Client Profile)

, or if you created a separate HTTP/2 profile for server-side traffic, select the profile from the list.

For the

HTTP MRF Router

setting, select the check box. For example:

From the

Default Pool

list, select a pool that is configured to serve HTTP/2 traffic.

Click

Finished

.

The HTTP/2 virtual server is now ready to listen for HTTP/2 traffic and send the traffic to the assigned server pool.

View statistics for an HTTP/2 full-proxy deployment

You can view statistics for either client-side or server-side HTTP/2 traffic.

On the Main tab, click

Statistics

Module Statistics

Local Traffic

From the

Statstics Type

list, select

Virtual Servers

.

By default, this displays the list of virtual servers on the BIG-IP system.

In the Virtual Server column, click the relevant virtual server name.

Along the top of the screen, click the

Statistics

menu.

In the Profiles area of the screen, from the

Select Profile

list, select an HTTP/2 profile.

After you perform this task, the BIG-IP system displays statistics pertaining to the traffic associated with the HTTP/2 profile you selected.

you can use non tls h2c on client side or server side or both.  
note: it’s not recommended for client side due to client compatibility matter.

Thanks for everyone’s replies. So, since all major browsers (Firefox, Chrome, Edge, Safari, and so on) only support HTTP/2 over TLS, it would appear we need to use SSL profiles for both, the client side and server side connections, unless we use h2c???

Thanks…

you can use h2c on server side regardless of how the client is because vserver is proxy.

however, i prefer to keep server side using simple http1.1 with oneconnect.  
simultaneous requests of http2 or http3 is heavier to be handled in webserver than 1 by 1 of http1.1,  
also no need to use f5 mrf profile.

on client side, use newer reliable udp based http3 instead of http2.  
it will reduce load in client and network due to udp based.
