Provided L2VLL to metro customer. He is able to access all systems though it. But two linux systems have problem. Problem starts like this.
Location A ------------------------- Location B
From location A customer will initiate ping to Location B from two problem systems. We will see their MAC in Location A customer port and Location B trunk port. It is perfect, but after some time we will see the same MAC's on Location B customer port and systems loose ping response.
For this we have run wireshark in Location B customer port and observed 'gratuitous arp' causing this. How to resolve this issue. Can we do something on switches to prevent this problem. Customer doesn't have backup ISP link.
