我尝试通过“br0”将流量路由到 10.2.129.0/24，但最终以“lo”结束。
知道哪里出了问题吗？
# ip route show
default via 192.168.2.1 dev eth0
10.2.129.0/24 dev br0 proto kernel scope link src 10.2.129.8
192.168.2.0/24 dev eth0 proto kernel scope link src 192.168.2.210
224.0.0.0/4 dev br0 scope link

来自的消息10.2.129.8不是对 ping 的响应，而是来自本地主机的消息，告诉您它无法将 ping 发送到10.2.129.1。
