Actually i don't know detailly
 
I check my system, it was set to TYPE=Vlan. 
I just guess that the reason was wrong ifcfg-setting. 
 
 
Before:
[ifcfg-eth0.10]DEVICE=eth0.10TYPE=EthernetVLAN=yesVLAN_ID=10PHYSDEV=eth0 
 
After
[ifcfg-eth0.10]
DEVICE=eth0.10
TYPE=Ethernet
VLAN=yes
BOOTPROTO=none

  11:11:11:11:11:11 MAC Address is just an example.
 
I solved this problem!
The real problem was the wrong set of ifcfg.... 
 
Thank you for your interest.

Can you try using another mac address instead of using 11:11:11:11:11:11, say 10:11:11:11:11:11? This will make the mac address a unicast address.  From: 이지찬

 No, it is not multicast packet...
Any packet the macaddress is changed...

Addition... my setting is so simple.
[PC1]
br1
 ----- eth0.10 (To PC2)

And... system network...

ifcfg-br1
 DEVICETYPE=ovs
 DEVICE=br1
 TYPE=OVSBridge
 IPADDR=10.205.128.1
 ......
 
ifcfg-eth0.10-ovs
 DEVICETYPE=ovs
 DEVICE=eth0.10
 TYPE=OVSPort
 OVS_Bridge=br1

ifcfg-eth0.10
 DEVICE=eth0.10
 TYPE=Ethernet
 VLAN=yes
 VLAN_ID=10
 PHYSDEV=eth0

ARP : PC2 [ARP Request] -> PC1 [ARP Reply]
 
PC2's Image. 
 
No problem in PC2. 
 
PC1's Image
 
But, Cause problem in PC1. 
 
Strangely change MAC Address in Received packet.
At 11:11:22:22:22:22,
11:11 is original source mac address(11:11:11:11:11:11)'s end 16bits.
22:22:22:22 is original destination mac address(22:22:22:22:22:22)'s begin 16bits.
 
I had never seen these problems... 
 
How can I solve this problem?
