I'm getting the following error - ifconfig: BRDGADD ath0: Invalid argument
Given the following commands (which work for my tap interface with
qemu on 7.1, but apparently not with two regular network cards on
6.3):
sudo kldload if_bridge
sudo ifconfig ath0 down
sudo ifconfig rl0 down
sudo ifconfig bridge0 destroy
sudo ifconfig bridge0 create
sudo ifconfig bridge0 addm ath0
sudo ifconfig bridge0 addm rl0
sudo ifconfig bridge0 up
sudo ifconfig ath0 up
sudo ifconfig rl0 up
sudo dhclient bridge0
ifconfig
I get the following output:
[steve@aire /usr/home/steve]$ bridge
kldload: can't load if_bridge: File exists
net.link.tap.user_open: 1 -> 1
net.link.tap.devfs_cloning: 1 -> 1
