L2FIB RP がアグリゲータの場合に、その L2FIB RP で学習した詳細を取得するためのエントリを確認します。ルート プロセッサ(RP)のエントリは、ライン カードから取得した集約エントリです。MAC 移動の場合、同じ MAC が異なる状態になることがあります。これは、RP
集約エントリに表示されます。RP は、MAC ラーニング アルゴリズムに従って、L2RIB に送信する更新を決定します。

RP L2FIB によって更新される L2RIB 内のエントリを確認します。エントリを確認するときは、次の点に注意してください。
-
L2VPN としてのプロデューサ、リモート IP としての NH を持つエントリは、リモート ピア ゲートウェイから学習されます。これらのゲートウェイは BGP から学習され、EVPN に更新されてから L2RIB に更新されます。そのため、これらのエントリはローカル
IP-MAC ラーニングによるものではありません。
-
L2VPN としてプロデューサ、ローカル バンドル インターフェイスとして NH を持つエントリは、MH-AA ピア ゲートウェイからの同期済みエントリです。
-
ローカルとしてプロデューサ、ローカル バンドル インターフェイスとして NH を持つエントリは、動的に学習されたローカル エントリです。
