Json 测试连接DHCP Kea/ISC DHCPDISCOVER数据包\u NAK\u 0001

DHCP服务器位于不同的网络上。我举起了Linux虚拟机，有两个接口。错误DHCPDISCOVER数据包\u NAK\u 0001

在Linux虚拟机上，我执行以下命令：

dhcrelay ip_dhcp -i name_interface

dhclient -v name_interface -s ip_dhcp

我通过“curl”发送的配置示例：

“池”：[

“客户端类”：“未知”
}
],
“有效寿命”：86400，
“保留”：[]
}
]
}
]
}
}

预期结果： 成功发布IP地址

实际结果： 错误[kea-dhcp4.坏数据包/26218]dhcp4_数据包_NAK_0001[hwtype=1 ]，cid=[无信息]，tid=0x23acf436:未能为其选择子网

---

传入数据包src 172.100.100.100，类型为DHCPDISCOVER

问题在于客户端类，无法及时知道子网选择

在选择子网后确定是否为给定客户机保留，因此不可能使用“已知”/“未知”类来选择共享网络或子网
