Hyper-V, Chr, wrong mac in neighbor list

Tue Oct 18, 2022 10:32 am

Source:
Windows Server 2016 standard, Hyper-V
Chr 6.48.6
Two interface: ethernet and bridge with it.
Mac address on interface and bridge (admin-mac) the same from Hyper-V virtual machine (00:15:xx:xx:xx:xx)

In neighbor list in other MT i can see chr with two mac addresses:
mac from chr (00:15:xx:xx:xx:xx) and mac from Hyper-V server interface.

Why is the host machine mac visible?

On this CHR router, there are only two interfaces connected from the HV. Their "native" mac addresses start with "00:15:5D".

There are no other interfaces (bridge etc).

Where the "E4:11:5B" addresses come from is unknown. There is no mention of these macs in the configuration.

Where do wrong mac addresses come from? How do I get rid of them???
