Enter configuration commands, one per line.  End with CNTL/Z.

!--- Enable virtual private dial-up networking.


2621(config)#vpdn enable

!--- Enters VPDN group configuration mode for the specified VPDN group.


2621(config)#vpdn-group 1

!--- Enters VPDN accept-dialin configuration mode 
!--- and enables the router to accept dial-in requests.

2621(config-vpdn)#accept-dialin

!--- Specifies which PPTP protocol is used.

2621(config-vpdn-acc-in)#protocol pptp

!--- Specifies the virtual template that is used 
!--- in order to clone the virtual access interface.

確認

このセクションでは、設定が正しく動作していることを確認するために使用できる情報を提供しています。

Output Interpreter Tool(OIT)(登録ユーザ専用)では、特定の show コマンドがサポートされています。 OIT を使用して、show コマンド出力の解析を表示できます。

  • show debug —解決するために現在 有効に なる debug コマンドを表示する

  • show user — 現在ログオンされるユーザおよびステータスを表示する

  • show ip route connected —ルーティング テーブルの現在のステートを表示する

  • show vpdn — アクティブレイヤ 2 トンネルプロトコル(L2TP)についての情報をまたはバーチャル プライベート ダイヤルアップ ネットワーク(VPDN)の Layer 2 Forwarding (L2f) プロトコルトンネルおよびメッセージ識別子 表示する

show debug コマンドの出力例を次に示します。

2621#show debug
PPP:
  PPP authentication debugging is on
  PPP protocol negotiation debugging is on


VPN:
  VPDN events debugging is on
