# Protect Neighbors Discovery - MikroTik Script RouterOS

    Mikrotik has a protocol that can broadcast domains through layer 2 so that Mikrotik devices can find each other if they are on the same layer 2 network, the name is Mikrotik Neighbor Discovery Protocol (MNDP). Devices that support MNDP and CDP can find or know other router information such as Router identity information, MAC-Address, and IP-Address. The easiest example when we are going to do winbox in the Neighbors tab, we will see some router information that is connected to layer 2 with our Network Info.

    # Hide Discover Interface Broadcast
    /ip neighbor discovery-settings set discover-interface-list=none
    # Show Discover Interface Broadcast
    /ip neighbor discovery-settings set discover-interface-list=all
