Hosting multi public subnets on BIG IP LTM

Hello everyone,

 

 

I'm new on F5 BIG IP LTM and I'm working on re-engineering a web hosting infrastructure. Actually, we are encountering an issue on the current public IP range, all IP addresses in the range are used.

 

The idea is to acquire a new /24 subnet and add it to F5 and continue to map VS/Public IP address (VIP + GARP).

 

My question is simple, is Big IP LTM can do that trick ? If yes, can I do that just by adding a new interface in the new subnet with the appropriated route ? If not, what are the potential solutions to solve the problem ?

 

 

Thank you

 

regards,

    anyway, you may not need to add route if all traffic is inbound. return traffic will be sent to mac address it comes by auto last hop feature.
