Dynamic ARP problem

Dear Experts,

 

 

I have two pairs of load balancers installed and have cascaded these two pairs. All four load balancers are running 9.3.1 OS. Each pair is working as Active/Passive.

 

My problem is that these two pairs can not communicate with each other and cant even ping to each other even when they are connected directly with a cross-over cable. I tried to find the reason and found out that in the dynamic ARP table of each load balancer, I have all nodes and routers MAC addresses, except for the other pair's MAC address which is being shown as resolved, but is ff.ff.ff.ff.ff.ff which is a broadcast MAC address.

 

Is there any limitation or any software bug when cascading load balancrs?

 

 

Looking for your advices
