LTM and presenting multiple mac address for VS

Guys

 

 

Were faced with a problem where by a router is not load balancing traffic equally between the router itself and the L2 switch downstream , this is most visible on a VS that exceeds 1gb traffic.

 

 

 

(Router) --[2 x1gb L2 links]-> (L2 switch) --[ 4gb trunk]->(BigIP.9.4.6)

 

 

 

The router vendor has advised that the router is using a mac hashing algorithm to send traffic to the destination ,and in our scenario 95% traffic is for one VS that exceeds 1gb , therefore due to the load-balancing inconsistencies of the router across their aggregated Ethernet trunk we have one link completely saturated and hardly any traffic across the other.

 

 

 

Question:

 

as the router is load balancing on the mac of the VS , is there some way creating 2 mac address for a VS ... or will this just cause more problems that what it could fix ?

 

 

 

 

 

Any toughs welcomed ...

 

 

Thanks
