Greetings, Following this article and it appears the LTM is aware of the fact that the device is in a high-availability configuration.

https://support.f5.com/csp/article/K15367

I modified the pool (per article) and when tab completing, options of the device names for the devices in the HA pair. This seems to be how the system differentiates:

 modify ltm pool ssh_pool gateway-failsafe-device
Configuration Items:
  ltm2.test.net    ltm1.test.net

Hi,

 

I can do all what is described in the article, and it's working. If my gateway pool went down Failover occurs.

 

That is not an issue here. I wonder how to define separate default gateways per node using Routes.

 

If I will define default gateway on one device after sync it will be propagated to other, so both will have te same one.

 

Now if I will define wildcard VS (ForwardingIP) for internal host this VS will use same gateway no matter which node will be active.

 

But my goal is to be able to use different default gateway depending on which node is Active - assume that each node is connected to network on ext side using different subnets. So one is going out VLAN1 -> GW1 -> Internet second VLAN2 -> GW2 -> Internet based just on routing table.

 

Seems to be impossible - or I am wrong?

 

I know that I can monitor separate GW on each device but those GW can not be default gateways because only one entry in Routes define DG and is shared by both nodes.
