Design Ideas for Routing Traffic Between Two F5 LTM Appliances with Point-to-Point Fiber Connections

Hello Community, I have a network architecture where I have two F5 LTM appliances, let's call them F5_A and F5_B, each connected directly with 4 fiber cables in a point-to-point configuration. My go...

Hi Gmiretsky,

About the four fiber cables, the most logical solution would be the use of link aggregation; create a trunk with for links and select L3 hashing to balance the traffic via the links in the trunk.

See: https://my.f5.com/manage/s/article/K1689 and https://my.f5.com/manage/s/article/K13562

Next, you'll need one Forwarding (IP) virtual server on each F5. Make sure to disable 'Reset on Timeout' and enable 'Loose initiation' in the FastL4 profile to let F5 act as a common router would do.

See: https://packetpushers.net/blog/stateless-routing-f5-ltm/

Have fun,
