CRS default config: Bridge and Interface MAC in IP Neighbors

RouterOS General
1

I have several CRS connected with 10G fiber using the default config.
Now every switch is listed twice in IP neighbors: one time with interface MAC and switch model and the second line is the bridge MAC without any additional information and 0 uptime.

Is this a bug or is there a way to hide those entries?

I think that’s because you run neighbour discovery on “all” interface list.
Create a list containing only the bridge (or only physical interfaces).
Then open “discovery settings” and choose that list.

Same issue, suggested solution doesn’t help. Hardware CRS109, CRS125, RB960PGS.
The lists duplicate items always contain the bridge mac address without proper details and the discovery interface mac address with proper details. (just like in the original op post)

There are other threads about this same issue. It was introduced in an upgrade version within the past six months or so. It’s pretty clearly a bug.
