HA config

Hi,

 

i hv 2 f5 , and will configured as HA. https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos_management_guide_10_1/tmos_selfips.html gone through the Q&A and found some said required floating IP..

 

here is the settings:

 

F5-1 and F5-2 as active standby IP add configured respectively on both devices

Internal Self-IP as vlan55 Internal Floating -IP as vlan55 HA-IP use vlan_HA Internal VLAN ID - VLAN_HA VLAN HA_ID - default vlan id

 

both device use the same VIP n pool members

VIP address pool members name 1 pool members name 2

 

i had completed the HA without use of floating IP. i still can do fail-over from active to standby and vice-versa.

 

i have doutbs as below:

 

if floating ip still necessary ? how to check ? if required to configured floating ip for HA Failover- what is the steps (besides of create Network ›› Self IPs , I created a name called floating__ip) what is the next steps?

 

application delivery
availability
deployment
design
LTM

    When using HA in active/standby mode the virtual servers will move to be active on the device which is active ( via Gratuitous ARP ).

     

    Where you are using the F5 without SNAT or using it as a router then you also have self-IPs that are required to float to the active device. If you use SNAT and no network virtual servers then you don't need the floating self-IPs.

     

    Look at this solution article for best practise on v10: https://support.f5.com/kb/en-us/solutions/public/11000/700/sol11736.html
