。

arp -a
出力は次のとおりです。
[dolphin@MiWiFi-R4CM-srv network-scripts]$ arp -a
? (192.168.31.29) at <incomplete> on br0
_gateway (192.168.31.1) at 50:d2:f5:7c:4a:60 [ether] on wlo1
? (192.168.31.30) at <incomplete> on br0

ゲートウェイアドレスをpingできないのはなぜですか?
答え1
問題は、ゲートウェイのあるネットワークである同じネットワーク()を共有するbr0
ことです。wl01
192.168.31.7/24
別のネットワークを割り当てるとwl01
問題が解決します。
192.168.31.1
wl01
正しいデバイスで明示的なパスを作成したり、ブリッジに追加したりすることもできます。
