00:aa:bb:01:23:45

Hello

By accident I noticed several of my VPLS instances have 
00:aa:bb:01:23:45 in the MAC table. We never sent anything just received 
a little traffic from that. Obviously not a real MAC address so I tried 
to search Google for it. I find several hits with apparently ADSL users 
doing pppd (which we do not have).

Anyone have any idea what this could be?

Regards,

Baldur
