howto enable routing between two vlans in f5 bigip load balancer so that two different vlans can communicate between each other.  One vlan is for external clients and second vlan is for internal servers

    You create a network VS of type forwarding (IP). Unless you want something slightly weird, set the protocol to 'all protocols' and you have the choice of enabling or disabling VLAN's and tunnels. Slightly unusual from a 'normal' VS there's no VS address or port. But you do specify a destination (e.g. 0.0.0.0/0 for all traffic).

     

    The forwarding will respect your routing table. And you can apply iRules etc. You can SNAT etc as well if you really need to.

     

    The world is your oyster as they say.

     

    Normally you'd use floating self-ip's for the gateway address. And if you want to get really fancy you can use route domains etc.
