ISR4321のBRIポートが使用出来ない BRI on ISR4321 doesn't work

Level 1

下記のコンフィグを同様に流し込むも、ISR4321ではBRIポートを使用して通信が出来ません。

 

【前提情報】

■1812-J C181X-ADVIPSERVICESK9-M 12.4(6)T2

■ISR4321 IOS XE 16.09.03 X86_64_LINUX_IOSD-UNIVERSALK9-M

■4321にはNIM-4BRI-S/T BRI Module(NIM-4BRI-S/T)を使用

■疑似交換機を使用し、拠点側にはグローバル番号"11"、対向側には21を割り当て

■下記のコンフィグと同一のコンフィグで1812-Jはルーター間で疎通が成功する

■ISR4321 2機を使用した下記構成ではPingが成功しない

■Ping実行時、下記debugコマンドは有効化済みですがAttemptingさえも現れない

 

<構成>

[拠点側ルーター(ISR4321)]BRI0/1/0-----[疑似交換機]-----BRI0/1/0[対向側ルーター(ISR4321)]

 

諸兄の知恵をお貸し願えませんでしょうか。

こんにちは

旧機器からの IOS-XE 機器へのマイグレーション時に良くある問題として、以下の記事があります。レガシーDDRは非推奨となりますので、ダイヤラプロファイルの設定を試してみてはいかがでしょうか。

ISDN DDR接続 : 筐体リプレイスメント、ソフトウェアアップ グレード後、ダイヤルアップの動作がおかしいと思ったら
