bridge を作ってみる

$ sudo -s
# ip link add name br0 type bridge
# ifconfig
br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        ether 82:db:31:03:84:ed  txqueuelen 1000  (イーサネット)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 2  bytes 762 (762.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

bridge と network interface をくっつける

# brctl addif br0 eth0
# ifconfig
br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 169.254.98.203  netmask 255.255.0.0  broadcast 169.254.255.255
        ether xx:xx:xx:xx:xx:xx  txqueuelen 1000  (イーサネット)
        RX packets 22  bytes 1840 (1.7 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 21  bytes 4170 (4.0 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

dhcpcd で br0 にアドレスを振り直す

# dhcpcd -k
# dhcpcd -n -H br0
# ip addr show
