例:複数インスタンスLDPの設定
プライマリ LDP インスタンスは、 [edit protocols]
階層レベルで設定されます。
[edit routing-instances routing-instance-name protocols]
階層レベルで ldp
ステートメントを使用して、LDP の特定のインスタンスを設定できます。これにより、特定の VRF ルーティングインスタンスの LDP のインスタンスが作成されます。設定を正しくコミットするには、必要なすべての VRF ステートメントを指定し、LDP インスタンスにエクスポートおよびインポートポリシーを適用する必要があります。
プライマリインスタンスで使用可能なLDP階層レベルのほとんどは、LDPの特定のインスタンスでも使用できます。ただし、 no-forwarding
オプションは、LDP の VRF ベースのインスタンスでは機能しません。
図 1 キャリアオブキャリアネットワークの一例を示す図。CE3およびCE4は、AS 65010に存在するエンドカスタマー用のCEルーターです。AS 65020のVPNプロバイダーには、3種類のルーターがあります。PE3とPE4はエンドカスタマーに接続するPEルーター、CE1とCE2は中間キャリアCEルーターとして機能し、P2とP3は内部トランジットルーターです。AS 65030のPE1とPE2は中間VPNプロバイダにサービスを提供するPEルーターで、P0とP1は最上位キャリア向けのトランジットルーターです。
この構成を機能させるには、次の 3 つの主要なタスクを完了する必要があります。
-
VPN カスタマー CE と VPN プロバイダ PE の間に外部 BGP を設定します。
-
PE ルーターの両ペア間で VPN ファミリーを使用して内部 BGP を設定します(PE1 と PE2 の間の 1 つの IBGP 接続と、ルーター PE3 とルーター PE4 の間の 2 番目の IBGP 接続)。
-
残りのすべてのリンクでLDPと内部ゲートウェイプロトコル(IGP)接続を確立します。この例では IGP として OSPF を使用していますが、任意の IGP を使用できます。
このキャリアオブキャリアの複数インスタンスLDPの例を裏付ける情報を 表 1にまとめています。

設定タスクはルーターCE3から始まり、ルーターごとにVPNプロバイダーネットワークの最初の部分を通って、AS 65020の2番目のVPNプロバイダークラスターを経由してキャリアASに移動し、2番目のVPNカスタマールーターCE4で終了します。
ルーターCE3は最初の顧客ルーターであるため、ルーターCE3と接続されたVPNプロバイダールーターPE3の間にEBGPを設定します。また、ルーターCE4とのIP到達性を可能にするために、ルーティングポリシーを使用してループバックアドレスをBGPにアドバタイズする必要があります。
ルーターCE3

ルーターPE3では、設定タスクがより複雑になっています。VRFインスタンスでルーターCE3へのEBGP接続を完了し、VPNプロバイダーのルーターCE1を指すインターフェイスでMPLSとLDPを有効にし、AS 65020の遠端にあるルーターPE4に到達するようにIBGPのプライマリインスタンスを設定する必要があります。
最後に、すべてのBGPトラフィックと直接接続されたインターフェイスをBGPコミュニティに配置するアウトバウンドVRFポリシーと、ルーターPE4から同様のBGPコミュニティトラフィックを受け入れるインバウンドVRFポリシーを設定します。
ルーターPE3

コア キャリア ルーター PE1 で、OSPF、LDP、MPLS、および IBGP のプライマリ インスタンスを( family inet-vpn
オプションを使用して)設定し、ルーターをネイバー ルーター PE2 に接続します。次に、セカンダリ インスタンスを確立して、複数インスタンス LDP を実装します。この例では、ルーターPE1がルーターCE1と通信できるように、LDPとOSPFを有効にします。セカンダリインスタンスでは MPLS は必要ありません。
最後に、ルーターCE1から来るすべてのLDPトラフィックをBGPコミュニティに配置するアウトバウンドVRFポリシー、このコミュニティトラフィックをルーターPE2に送信するエクスポートポリシー、およびルーターPE2から同様のBGPコミュニティトラフィックを受け入れるインバウンドVRFポリシーを設定します。このステップでは、VPNプロバイダのLDPトラフィックをキャリアのBGPセッションにトンネリングします。

機能の検証
複数インスタンス LDP 設定の適切な動作を確認するには、次のコマンドを使用します。
-
show ldp database
-
show ldp interface
-
show ldp neighbor
-
show ldp path
-
show ldp route
-
show ldp session
-
show ldp statistics
これらのコマンドの表示出力は、1つの違いを除いて、以前のJunos OSリリースと同じです。インスタンス名を引数として使用できるようになりました。
これらのコマンドにインスタンス名を含めると、指定した LDP インスタンスの情報が表示されます。たとえば、コマンド show ldp neighbor instance crockett
は、 crockett
という名前の VRF インスタンスのすべての LDP ネイバーを表示します。逆に、インスタンス名のない show ldp neighbor
には、プライマリインスタンスに関連付けられているLDPネイバーが表示されます。
