L3 routing on F5

Hi,

WE have a customer who is asking for configuring 2 F5 devices as active active and to be connected to existing Active Active Firewalls and without a switch in between - HE need to connect direct cables between the F5 and Firewall Boxes

When we try the same VLAN between F5 and Firewalls, We found a loop

When we try the same setup with 1 VLAN and a switch in between, It was good and redundancy work good and there is no loops

We think of using 2 VLANs between F5 and FWs , but we found that we'll need to configure routing to achieve the redundancy in case one box fail, we'll route the affected subnet the other other box. Is F5 good for routing and is F5 support only static routes or it could do any routing protocol ?

Also please advise for a better solution for our case if there is a better one [to have F5 as Active Active connected to 2 FWs active Active directly without a switch in between]

Thanks Haitham
