    ルーティング対象ネットワークで、リモート ブリッジが設定されたイーサネット ネットワークへの接続が必要な状況では、シリアルまたは ISDN インターフェイスを PPP ハーフ ブリッジとして機能するように設定できます。リモート ブリッジへの回線は仮想イーサネット インターフェイスとして機能し、ルータのシリアルまたは ISDN インターフェイスはリモート ネットワークと同じイーサネット サブネットワーク上のノードとして機能します。

    ブリッジは PPP ハーフ ブリッジにブリッジ パケットを送ります。PPP ハーフブリッジは、ブリッジ パケットをルーテッド パケットに変換し、それを他のルータ プロセスに転送します。同様に、PPP ハーフブリッジはルーテッド パケットをイーサネット ブリッジ パケットに変換し、それを同一イーサネット サブネットワーク上のブリッジに送ります。


    :インターフェイスは、ハーフブリッジとブリッジの両方の機能を持つことはありません。Cisco IOS(R) ソフトウェアは、1 イーサネット サブネットワークごとに PPP ハーフブリッジを 1 つだけサポートします。

    設定

    ルータ 1
    これは、「フルブリッジ」で、ダイヤルするように設定されたルータです。

     Current configuration:
    
     !
    
     version 11.2
    
     !
    
     isdn-3#wr t

    注:この設定では、ルータがダイヤルするためのブロードキャストがダイヤラ マップ上に必要になります。また、グローバル設定で ip routingオフにされています。
    ルータ 2
    このルータはハーフブリッジとして設定されており、ダイヤラ マップ上に擬似の電話番号を持ちます。このルータはこのテストではダイヤルしません。

    デバッグおよび検証のヒント

    • debug ppp negotiation - クライアントが PPP ネゴシエーションを渡しているかを確認するためのものです(アドレス ネゴシエーションをチェックするとき)。

    • debug ppp authentication - クライアントが認証を渡しているかを確認するためのものです。11.2 よりも前の Cisco IOS ソフトウェア リリースを使用している場合には、この代わりに debug ppp chap コマンドを使用します。

    • debug ppp error - PPP 接続ネゴシエーションおよびオペレーションに関係するプロトコル エラーおよびエラー統計を表示するためのものです。
    • debug dialer - 対象トラフィックが検出された時間およびダイヤリングが始まった時間を確認するためのものです。

    • debug isdn events - ダイヤリングが始まったときに ISDN イベントが発生していることを確認するためのものです。

    • show bridge verbose - モデムのハードウェア状態を探すためのものです。

    • show interface bri0 1 2 - インターフェイスの状態を確認するためのものです。
    上記の debug コマンドを試す前に、「デバッグ コマンドの重要な情報」を参照してください。 Router 2 Rotuer 1
