Under Debian I need to bridge a vlan
eth0.1 and tap
tap0. Usually, when bridging a normal ethernet adapter with a tap I would include something along the lines of this in
auto br0 iface br0 inet static pre-up /usr/sbin/openvpn --mktun --dev tap0 pre-up /usr/sbin/brctl addbr br0 address 10.0.0.254 network 10.0.0.0 netmask 255.255.255.0 post-up /sbin/ip link set tap0 up post-up /usr/sbin/brctl addif br0 tap0 post-up /sbin/ip link set eth0 up post-up /usr/sbin/brctl addif br0 eth0 post-down /sbin/ip link set br0 down post-down /usr/sbin/brctl delbr br0 post-down /usr/sbin/openvpn --rmtun tap0 post-down /sbin/ip link set eth0 down
Now, I will admit it is not pretty (we manually create the tun and the bridge using the raw commands) although it is the most Debian-like means I've found. The problem comes when I want to replace
eth0 with a vlan, such as
eth0.1. The only way I can think of is manually adding
post-down commands to manually create the
eth0.1 vlan (with all others being configured the Debian way).
However, I am not totally sure then as the
post-down /sbin/ip link set eth0 down may break other
eth0.x vlans. Can someone suggest a cleaner means of accomplishing my goals?
