providing 2 default routes on the F5 LTM.

Folks, One of those basic questions. ;)   We have an existing F5 LTM which is running VIP's on a dedicated network segment. Let's take the segment as 1.1.1.0/24. We have a self-IP configured on...

 ,

 

Where is the L3/gateway of network 2.2.2.0/24 is configured?

If it is on the same switch where the gateway of network 1.1.1.0/24 is present, you can pass traffic for new network through the existing interface being used for 1.1.1.0/24 on F5. For this, you need to make interface as a trunk and pass all required VLAN. With this setup, the current default route on the F5 will be used as it is for new segment also.

 

Hope it helps!

    Thanks for the response Mayur.

     

    Yes, agreed. That is what the first option was. The L3 gateway is on the same network switch.

     

    The only risk was a downtime for the existing VIP's which are kind of critical.

    We wanted to get this activity completed without a maintenance window.
