Works as follows: 1. for every node take the ARP cache 2. for every record in the cache reconstruct two triplets: * the interface index -> the local interface name * the neighbour lladdr -> the remote node and interface name Issues: does not filter out fake lladdr, so CARP interfaces produce fake l2 edges within the cluster. )r!
