Overview
MikroTik Neighbor Discovery protocol (MNDP) allows to "find" other devices compatible with MNDP or CDP (Cisco Discovery Protocol) in Layer2 broadcast domain.
Neigbors
Sub-menu: /ip neighbor
This sub-menu lists all discovered neighbors in Layer-2 broadcast domain. It shows to which interface neighbor is connected, shows it's ip/MAC addresses and several Mikrotik related parameters. List is read-only.
As an example, you can see several RouterBoards and two Cisco routers:

Discovery configuration
Sub-menu: /ip neighbor discovery
In this menu is possible to change state of the interface whether it participates in neighbor discovery or not. If it does, it will send out basic information about system and process received discovery packets broadcasted in Layer-2 network. List of interfaces is automatically managed by RouterOS. Items in the list cannot be removed nor added. Default settings depend on interface type and current state.
| Property | Description |
|---|---|
| comment (string; Default: ) | Short description of an entry |
| disabled (yes | no; Default: ) | Whether item is disabled and do not participate in sending/receiving of discovery information. Added in v5.x |
| discover (yes | no; Default: ) | Whether to participate in sending/receiving of discovery information. Since v5.x left for compatibility with older scripts. |
