どうも、LANケーブル職人の優です!
さて、今回はYAMAHA RTX1210とSWX2200のタグVLANでネットワークを作ってみましょ~!
もくじ
VLANを行うどうなるの?
VLANとはバーチャルLANといいます。いくつも仮想的にネットワークを作る機能です。
- ネットワークの分離でセキュアに
営業部は総務部にアクセスさせない。ゲスト用の無線ネットワークを別に作るといったことも出来ます。 - ARPリクエストなどブロードキャストの分離
ブロードキャストドメインはVLANで区切ることが出来るので、各ホスト間のCPUの負担も軽減できてしまいます。100クライアント近くになったらVLANを考えましょう。
いい事尽くめのVLAN。使わないわけにはいかない、便利機能ですよね!
ルータ RTX1200
- VLAN1
192.168.101.0/24 - VLAN2
192.168.102.0/24 - VLAN3
192.168.103.0/24 - VLAN4
192.168.104.0/24 - VLAN5
192.168.105.0/24 - VLAN6
192.168.106.0/24 - VLAN7
192.168.107.0/24
ポートの構成
- LAN1
192.168.100.0/24 - LAN1/1
L2スイッチとの接続 - LAN2
WANです。NURO回線
L2スイッチ SWX2200-8G
- ポート1:VLAN1
- ポート2:VLAN2
- ポート3:VLAN3
- ポート4:VLAN4
- ポート5:VLAN5
- ポート6:VLAN6
- ポート7:VLAN7
- ポート8:ルータとの接続
VLAN1~7はそれぞれ疎通できない隔離設定。

よくある要望
- VLAN1とVLAN2のネットワークだけはお互いに疎通させたい。
- 他のVLAN間のネットワークの通信は遮断したい
Let’s cooking!
ここにVLAN1とVLAN2のフィルターがあるじゃろ
ip filter 600000 reject 192.168.101.0/24 192.168.102.0/24 ip filter 600006 reject 192.168.102.0/24 192.168.101.0/24
フィルターの適用がこうなっているから…これを
ip lan1/1 secure filter in 600000 600001 600002 600003 600004 600005 600042 ip lan1/2 secure filter in 600006 600007 600008 600009 600010 600011 600042
こうじゃ!
ip lan1/1 secure filter in 600001 600002 600003 600004 600005 600042 ip lan1/2 secure filter in 600007 600008 600009 600010 600011 600042
VLAN1からVLAN2にpingを打ってみよう
はい、通りました~。
