MikroTik Neighbor Discovery Protocol (MNDP)

Document revision 1.6 (23-May-2003)
This document applies to the MikroTik RouterOS v2.7

Contents of the Manual


The MikroTik Neighbor Discovery Protocol (MNDP) eases network configuration and management by enabling each MikroTik router to discover other connected MikroTik routers and learn information about the system along with features which are enabled. The MikroTik routers can then automatically use learned information to set up some features with minimal or no configuration.

MNDP features:

MikroTik RouterOS is able to discover both MNDP and CDP (Cisco Discovery Protocol) devices.

M3P (MikroTik Packet Packer Protocol)


MNDP basic function is to assist with automatic configuration of features that are only available between MikroTik routers. Currently this is used for the 'Packet Packer' feature. The 'Packet Packer' may be enabled on a per interface basis. The MNDP protocol will then keep information about what routers have enabled the 'unpack' feature and the 'Packet Packer' will be used for traffic between these routers.

Specific Properties:

MikroTik Neighbour Discovery Protocol Setup

Submenu level : /ip neighbor discovery

Property Description

name (read-only: name)- interface name for reference
discover (yes | no; default: yes) - defines if discover is enabled or disabled


To disable MNDP protocol on Public interface:
[admin@MikroTik] ip neighbor discovery> set Public discover=no
[admin@MikroTik] ip neighbor discovery> print
  0 Public    no
  1 Local     yes

Listing the Discovered Neighbours

Submenu level : /ip neighbor

Property Description

interface (read-only: name) - local interface the neighbor is connected to
address (read-only: address) - IP address of the neighbor router
mac-address (read-only: mac-address) - MAC-address of the neighbor router
identity (read-only: string) - identity of the neighbour router
version (read-only: string) - router version of the neighbour router
unpack (read-only: none | simple | compress-headers | compress-all) - identifies if the interface of the neighbour router is unpacking 'Packed Packets'

As you can see, not only MikroTik RouterOS routers were discovered, but HP Procurve 2524 switch and Cisco 350 Series Wireless Bridge
