This post is second part for configuring F5 BigIP LTM v11.5.3  High Availability. You can find other related posts in this blog:

1. Topology:

Logical Topology:

Four Networks:

  • Management Network – Network Adapter 1 in F5 VE – 192.168.2.26/24 and 192.168.2.27/24
  • Internal Network – Network Adapter 2 in F5 VE – 10.1.1.1/24 and 10.1.1.2/24
  • External Network – Network Adapter 3 in F5 VE – 172.17.3.1/24 and 172.17.3.2/24
  • HA Network – Network Adapter 4 in F5 VE – 192.168.1.1/24 and 192.168.1.2/24

Networking Configuration in my Virtual Lab Environment:

2. Mgmt Interface Configuration:

Log in with username root and password default.

There are two different ways to do F5 VE management port settings. One is from part 1 using tmsh commands. Or we could use config wizard as show below.

After logged in, use config wizard to change your Mgmt Interface IP address and default route.

3. Activate Trial License for both VE

You can get your 90 day free trial license from https://www.f5.com/trial/big-ip-ltm-virtual-edition.php

After entered the registration key into your VE license page, you will get a dossier to generate license from F5 license activation page – https://activate.f5.com/license/dossier.jsp

admin/admin is the default Web GUI account. Here is how your VE looks like after activated license.

4. Create VLANs

Interface 1.1 -> Internal Vlan -> 10.1.1.1 and 10.1.1.2, floating IP is 10.1.1.3
Interface 1.2 -> External Vlan -> 172.17.3.1 and 172.17.3.2, floating IP is 172.17.3.3
Interface 1.3 -> SYNC HA Vlan -> 192.168.1.1 and 192.168.1.2

4.1 Using Wizard

 



 



 



 






 



 


 





 

4.2 Manually

 



 



 



 
 


You can verify self ip addresses by logging in F5 VE and pinging each other.

5. Device Group



 

 



 




Notes:

Fix the F5 sync state disconnected issue:

  1. Device Groups >(device group previously setup) put both boxes back to available.
  2. Delete the existing device group.
  3. Reset Device Trust. Choose Generate New Self-Signed Authority.
  4. REBOOT THE VE!!!!!!
  5. Device Trust>Peer list. Establish peering. (It is able to see peer no problem.)
  6. Create device groups. “test-sync-failover”. Put both devices in “includes”. and check Network Failover.
  7. Confirm both devices are in the Device List area.
  8. Overview>(click self device)>choose “Sync Device to Group”>Choose “Overwrite Configuration”>Sync


6. iApp
Getting Started with the iApp for HTTP applications
To begin the HTTP iApp Template, use the following procedure.
6.1. Log on to the BIG-IP system.
6.2. On the Main tab, expand iApp, and then click Application Services.
6.3. Click Create. The Template Selection page opens.
6.4. In the Name box, type a name. In our example, we use HTTP-app_.
6.5. From the Template list, select f5.http.
The HTTP template opens.

 

 




 
after I changed the string at ‘What HTTP request should be sent to check the health of each HTTP server?’ from default value ‘GET /r/n’ to ‘GET /HTTP/1.0/rnrn’, the virtual server’s availability becomes green.
