I have two links connecting two radio shops

I put two RB-750, one on each side and created a bounding with mode = broadcast, link monitoring mii-type 2 and transmit-hash-policy = layer-3-and-4. At first everything worked well, the load is divided, when one link falls the other continues to work normally, but there is a problem to ping the machines in the remote end I get ping (dup!) And this is causing a lot of problems in software monitoring network. Is there any way to solve this?

Thanks

post a torch output of the interface when you try to ping

The only problem is that the ping is done by a backup system between stores. And because of (DUP!) It is not working. Is there some setting that can be done to prevent this?
