ちなみにレガシーブリッジでは、VLANごとにブリッジの作成が必要 例) tap <-> br0_101 <-> eth0.101
- 設定事例集：インターネットマンションで使用する（BSシリーズ Gigaスイッチ）| BUFFALO バッファロー
※PVID とは、Port VLAN ID の意味で、ポートに設定されたPVID により、タグ無しのパケットを受信した場合、どのVLAN に送信するかを決定します。タグ付きのパケットを受信した場合は、PVID とは関係なくタグの送信するパケットのVLAN IDを参照し、送信先のVLAN を決定します。
- VLAN ID 1 は多くのインテリジェントスイッチでマネージメント用に予約されているため、非推奨
- mitty@vlan-gw:~$ sudo vconfig add eth1 1
Added VLAN with VID == 1 to IF -:eth1:- WARNING: VLAN 1 does not work with many switches, consider another number if you have problems.
Bridging VLAN
- 概念図
- 目的
- vlan-gwのeth0にL2で抜けるルートがvlan-node上に欲しい
- vlan-gwのeth0 <-> eth1で直接ブリッジするのは困る
- vlan-nodeは本来NAPT下にある、など
- VLANにすることで、NICを増やしたりすることなく複数サブネットを得る
make bridge on vlan-gw
- mitty@vlan-gw:~$ sudo vconfig add eth1 10

- VLAN ID 10でのDHCP requestに対して、192.168.111.1のdhcpdがVLAN ID無しでreplayしている模様
- DHCPd(isc-dhcp-server)はtaggedかどうかを無視する？

VLAN with VMware Workstation on Windows
- WindowsはOSとしてはtag VLANに対応して居ない
- vmware workstation は VLAN 非対応
ホストOSで、Tag VLANを切って、その上で、vmware が対応するタグVLAN I/F をゲストOSに割り当てればよい。そういう意味では、ゲストOSからはTag VLANではなくて別インターフェースになる。 使いにくいといえば使いにくい。特にWindowsホストOSの場合はWindows自体がTag VLAN に対応していないのでめんどう。Ethernetカード専用のドライバでの対応になる。

- Windowsホスト上にVMware WorkstationでLinuxゲストを作り、仮想NICをブリッジしてVLAN deviceを作成しても、うまく疎通出来ない

- requestはVLAN ID 10となっているが、replyはVLAN IDが無くなってしまっている
