Hi:
thanks for your reply. you say the bridge interface should take the ip
address,
not the nic. that's important. i think i go to the wrong direction. i want
nic
(eth0,dummy0) to have ip address, not br0. it seems not what linux bridge
designed to do...
by the way, i found if i set mac address manually :(eg: arp -s
192.168.10.254 x:x:x:x:x:x),
then i can ping 192.168.10.254 via eth0. but i can never make dummy0 work in
any way.
Regards,
tbsky
