The problem came back, and it's similar to: Kernel Warning - Received packet with own address as source address - #53 by Ellah1
Note: WifiAP-xx changes between 01...05 every 5-8 minutes randomly.

I ran
tcpdump -i br-vl10 -evn not host 10.20.10.61 and ether host a4:2b:b0:de:86:21
on WifiAP-01 and got:
(...a lot more of the same...)
09:31:44.368052 a4:2b:b0:de:86:21 > 01:00:5e:00:00:01, ethertype IPv4 (0x0800), length 1496: (tos 0xc0, ttl 1, id 0, offset 0, flags [DF], proto IGMP (2), length 32, options (RA))

What can I do against this problem? Seems like a bug?!
