RecoverPoint hardware appliances and link aggregation

We have a cluster of 3 RPAs at each site and need to setup remote replication. Since we have two edge routers, we can only connect two appliances to one router and one appliance to the other. This obviously lead to question what happens if the router to which two appliances are connected fails. One appliance will not be able to handle the load of all three of them. Therefore, logical solution would be to aggregate the RecoverPoint links and remove the single point of failure in the router.

Is this at all possible? If so, how can this be configured.
