我在 ubuntu 上配置了 dhcpv6 服务器。我根据接口(interface) ID 为每个客户端定义了静态绑定(bind)。
但是当客户端请求时，DHCPv6 服务器上的分配失败。
“dhcpd [122762]:send_packet6:错误的文件描述符”
----在dhcpv6服务器上配置----
subnet6 2404:e801:1014::/48 {
host client-name-2404.e801.1014.5 {
host-identifier option dhcp6.interface-id "OLT3923.IOT xpon 0/2/0/1:2404:e801:1014::5";
fixed-address6 2404:e801:1014::5;
fixed-prefix6 b1a1:3003:1014:5::/64;
}
----系统日志消息----

最佳答案
用于 dhcpv6 服务器的接口(interface)也有用于其他功能的子接口(interface)。
删除子接口(interface)后，分配成功。
这看起来像一个限制/错误，但找不到任何文档。
