Using BigIP as a load balancer as well as a router

Hello All,

 

 

I am in a unique situation, where in the BigIP in my deployment is sitting inline between upstream and downstream routers. On the inside Vlan I've got subscribers who browse internet and on the Outside Vlan I've got the internet gateway. The BigIP is load balancing performance enhancing proxy servers in a transparent mode.

 

 

I want to ensure that the users that are supposed to hit the Performance Enhancement Proxy servers to be load balanced across the servers.

 

 

Other users who donot hit the Proxies should be routed.

 

 

From subscriber to internet I use default gateways like my subscriber side router uses BigIP as a default gateway, BigIP uses the router on outside Vlan as a default gateway.

 

 

From internet to subscriber, I use OSPF on BigIP and neighboring routers as well.

 

 

My question is for traffic from subscriber to internet can I simply use a default route entry in BigIP rather than configuring a Virtual server that has destination as 0.0.0.0 and uses internet routers as resources and applied on inside vlan??

 

 

Will addition of default route entry solve this?? And this way I do away with need of configuring a default_gateway virtual server!!!!

 

 

Please find the diagram under mentioned.

 

 

Suggestions are highly appreciated.
