在特定子网中配置 DHCPD 以使用选项 66

我正在尝试配置 DHCP 以使用选项 66 为 Sunray 瘦客户端提供 TFTP 服务器。特定子网中的客户端必须使用特定的 TFTP 服务器，以便为其提供特定于其子网的配置。我可以将选项放置在子网块中，如下所示

 subnet 192.168.1.128 netmask 255.255.255.128 {

    # don't let clients modify their own A records
    ignore client-updates;

    # options
    option subnet-mask 255.255.255.128;
    option broadcast-address 192.168.1.255;

    option domain-name "domain.com";
    option domain-name-servers 192.168.3.55, 192.168.3.56;
    option routers 192.168.1.129;
    option 66 ip 192.168.16.21;

    option ntp-servers 192.168.3.57;
    option interface-mtu 1500;
    ddns-domainname "dhcp.domain.com.";
    ddns-rev-domainname "dhcp.in-addr.arpa.";
    pool {
            failover peer "dhcp-failover";
            range 192.168.1.140 192.168.1.249;
    }

}

在 isc-dhcp-server 中我创建选项全局使用，然后在主机级别使用它。你应该能够使用供应商选项空间在子网级别也是如此。

option space SunRay;
option SunRay.FWSrvr code 31 = ip-address;      
option SunRay.FWSrvr 10.99.90.160;
option SunRay.AuthSrvr code 21 = ip-address;
option SunRay.AuthSrvr 10.99.90.160;
option SunRay.AltAuth code 35 = array of ip-address;
option SunRay.AltAuth 10.99.90.161, 10.99.90.160;

host 10.96.0.11 {
    vendor-option-space SunRay;
    hardware ethernet 00:ff:ff:ff:ff:ff;
    fixed-address 10.96.0.11;
}
