VIP A > Gateway A, VIP B > Gateway B

Hi Alex,

 

 

Have you tested this and found that return traffic to the client is not sent to the correct router? For the VIP response to the client, LTM can use a last hop pool instead of the default last hop destination:

Last Hop Pool

 

 

A setting that directs reply traffic to the last hop router using a last hop pool. This overrides the auto_lasthop setting. In cases where you have more than one router sending connections to the BIG-IP system, connections are automatically sent back through the same router from which they were received when the auto_lasthop global variable is enabled, as it is by default. If you want to exclude one or more routers from auto-lasthop, or if the global auto_lasthop is disabled for any reason (for example, you may not want it for an SSL gateway), you can use a last hop pool instead. (If auto_lasthop is enabled, the last hop pool takes precedence over it.)

 

Before configuring a last hop pool, you must first create a pool containing the router inside addresses.
