ネットワーク エンジニアが新しい GRE トンネルを設定し、show run コマンドを入力します。出力で何が検証されますか?
正解:C
The output verifies that the tunnel keepalive is configured incorrectly because they must match on both sites. In the provided configuration, SiteA has a keepalive of 5 seconds while SiteB has a keepalive of 6 seconds. For GRE tunnels to establish and maintain connectivity, the keepalive settings should be identical on both ends of the tunnel to ensure that both sides can detect if the tunnel becomes unreachable.
