Hi,
I have a VRRP towards a customer with with the master interface on an MX104 and the backup interface on an MX960. I have a problem with the traffic being asymmetric. Traffic towards the customer is running via the master while the return traffic is running via the backup. One thing that confuses me is that I see arp being resolved on both master and backup and probably that's why this asymmetry is happening. How come the arp is being resolved on both routers? Is this correct?
