Subject: Fw:Some question about 802.1Q VLAN

HI…I am a Linux VLAN user. Now, I encounter some question about 802.1Q VLAN in my wireless AP. My Linux kernel version is 2.6.31.

Plese see my setting:
           vconfig add eth0 10
           vconfig add ath0 10
           ifconfig eth0.10 up
           ifconfig ath0.10 up
           brctl addbr br0
          brctl addbr br1
          brctl addif br0 ath0
          brctl addif br0 eth0
          brctl addif br1 ath0.10
          brctl addif br1 eth0.10
          ifconfig br0 up
          ifconfig br1 up

The eth0 and ath0 is real network card in my AP,and the ath0 is the wireless card.

Question:
     Two station associate AP by wireless,the two station and AP use same VLAN setting like my describe.One station br0 Ip address is 192.168.1.10/24,br1 ip address is 192.168.2.10/24;other station br0 ip address is 192.169.1.11/24, br1 ip address is 192.168.2.12/24.The AP is used bridge the data from station.
  But now use station1 ping station2: ping 192.168.1.11,it is successed; ping 192.168.2.12,it is failed!!!
  I don’t know the reason about the fail situation ,I need some help.
  Thank you!
