How to find out what's on interface's first hop?

RouterOS General

Say you have mikrotikA, mikrotikB and mikrotikC.

Mikrotik B is connected to mikrotik A’s ether1 port.

Mikrotik C is connected to mikrotik B’s ether 2 port.

If you go to mikrotik A’s IP>neighbours you would see both mikrotik B and C on ether1 port. From this, you can’t conclude which of the two is on the first hop, that is, directly connected to that ether1 port.

I’ve also tried bridge > hosts but there is nothing akin to hop/first hop/TTL/whatever to conclude which is the FIRST device on that said port.

Is there a way this can be found out?

A bit logical.
For A , device C is effectively connected to ether 1.

You could use ROMON (if enabled on all devices and they all have to run ROS), it does show path and distance but then you need to make the link between MAC and ether port.

I’ve got around a 1000 Mikrotik devices. Connecting to each to create the link between MAC and ether port would be asinine. :frowning:

Thanks for the input, though.
