MNDP — MikroTik Neighbor Discovery Protocol

MNDP is the UDP broadcast/multicast protocol that RouterOS uses for automatic device discovery on the local network. It is the same protocol WinBox uses to find routers. Every RouterOS device participates by default.

Why This Matters for Agents

• /ip/neighbor on RouterOS is the CLI/REST surface for MNDP results
• WinBox's "Neighbors" tab is an MNDP listener
• Any agent implementing device discovery for MikroTik equipment needs MNDP
• The protocol is simple enough to implement from scratch — no library needed
