目次
概要
企業の社内ネットワークを構築する総合的な演習です。以下の技術を組み合わせて企業の3つの拠点を相互接続します。拠点間の接続は広域イーサネットをプライマリとして、インターネットVPN(IPSec VTI)をバックアップにします。
- VLAN
- SVI/ルーテッドポート(レイヤ3スイッチ)
- OSPF
- HSRP
- BGP
- NAT
- IPSec-VPN(VTI)
Part4は、インターネットをエミュレートするAS1とAS2を構築します。
Part1:拠点1の構築
Part2:拠点2/拠点3の構築
Part3:広域イーサネットの接続
Part4:インターネット(AS1/AS2)の構築
Part5:インターネットへの接続
Part6:インターネットVPNの構築

Part4:インターネット(AS1/AS2)の構築
要件
- AS1のISP11～ISP15でLoopback0のIPアドレスを利用してIBGPネイバーを確立します。ISP15をルートリフレクタとして設定します。
- ISP15でBGPルート100.1.1.0/24、100.1.2.0/24を生成します。また、拠点1、拠点2を接続しているネットワークアドレスをBGPルートとして生成します。
- AS2のISP21とISP22でLoopback0のIPアドレスを利用してIBGPネイバーを確立します。
- 拠点3を接続しているネットワークアドレスをBGPルートして生成します。
- AS1-AS2間でEBGPネイバーを設定して、AS間のBGPルートを交換できるようにします。EBGPネイバーでは、パスワード「cisco」でネイバー認証を行います。
- AS2から100.1.1.0/24へパケットをルーティングするときには、ISP13を経由するようにします。AS2から100.1.2.0/24へパケットをルーティングするにはISP14を経由するようにします。
AS1の設定
IBGPネイバー
AS1のISP11～ISP15でIBGPネイバーを設定します。IBGPネイバーは、Loopback0のIPアドレスで確立します。各ルータのLoopback0のIPアドレスは以下の通りです。
| ルータ | Loopback0のIPアドレス |
|---|---|
| ISP11 | 192.168.0.11/32 |
| ISP12 | 192.168.0.12/32 |
| ISP13 | 192.168.0.13/32 |
| ISP14 | 192.168.0.14/32 |
| ISP15 | 192.168.0.15/32 |
これらLoopback0のIPアドレスは、AS内のOSPFでルーティング可能です。
そして、ISP15はルートリフレクタなので、ISP11～ISP14はISP15とのIBGPネイバーを設定します。

ルートリフレクタのISP11でshow ip bgp sumamryコマンドでIBGPネイバーの状態を確認します。

BGPルートの生成
ISP15でnetworkコマンドによって、BGPルート100.1.1.0/24、100.1.2.0/24を生成します。また、ISP11で拠点1のグローバルアドレスの1.1.1.0/30と1.1.1.4/30をBGPルートとして生成します。ISP12で拠点2と接続している2.2.2.0/30をBGPルートとして生成します。
ISP15 BGPルートの生成
router bgp 1 network 100.1.1.0 mask 255.255.255.0 network 100.1.2.0 mask 255.255.255.0

ISP21-ISP22間でIBGPネイバーを設定します。それぞれLoopback0のIPアドレスを利用します。また、ISP21では拠点3と接続している3.3.3.0/30のネットワークアドレスをBGPルートとして生成します。
