When i configure MN(192.168.3.4)same subnet address with
AP(br0:192.168.3.3),its work. Thanks
I will unset all IP address on eth0 & wlan0 on AP.
my testbed just a small private wireless LAN,not NAT. Another thing is if
i want the MN roaming between this 2 AP(different Subnet),how can i
statically(manually) configure the routing between this 2 AP? it seem not
easy.
Later i will test on IPv6 routing & mobility testing
