You can assign a VLAN to a bridge (or whatever the proper expression is!). I don't know how it's done with "/etc/network/interfaces" but I do know how to do so with RHEL ifcfg files so I can extrapolate _something_ theoretical. But the use-case that I have for that is different and I'm not too sure how to transpose to yours, if it's at all possible. The use-case is for connecting VMs on one host to different VLANs (note: _different_ VLANs). So VM0's tap0 is added to br0.I, VM1's tap1 is added to br0.J, ethX (or bondX if you have bonds) is assigned to VLANs x and y and added to br0.I and br0.J respectively, and these bridges are assigned ip addresses. So trying to mimick ifcfg files from memory (and keeping in mind that in ifcfg files I'd have the equivalent of "allow-auto eth0", "allow-auto eth0.I", "allow-auto eth0.J" too but it doesn't seem to be needed in "/etc/network/interfaces"): iface eth0 inet manual iface eth0.I inet manual iface eth0.J inet manual allow-auto br0.I iface br0.I inet static bridge_ports eth0.I tap0 address ... netmask ... gateway ... <other_bridge_stuff> allow-auto br0.J iface br0.J inet static bridge_ports eth0.J tap1 address ... netmask ... gateway ... <other_bridge_stuff> So, in your case, assuming that you want a bridge: iface eth0 inet manual iface eth0.I inet manual allow-auto br0.I iface br0.I inet static bridge_ports eth0.I address ... netmask ... gateway ... <other_bridge_stuff> post-up ip address add ... dev br0.I -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
