  • Linux VXLAN driver and network namespace -

    I am trying to understand the vxlan driver code in linux kernel. The kernel version is: 3.16.0-29-generic.

    MAC learning database: used to keep track of the host locations in the LAN. For each unicast mac address, bridge maintains a mac learning database to decide which ports to forward based on MAC addresses, and if it can't find an entry for a given mac address, it will broadcast the frame to all ports except the one where it received the frame from.
