DHCP选项的格式如图1-2所示。一部分DHCP选项的内容由RFC 2132进行规定,如Option 3(路由器选项,用来指定为客户端分配的网关地址)和Option 6(DNS服务器选项,用来指定为客户端分配的DNS服务器地址),还存在一部分选项RFC没有统一规定,例如Option 43(厂商特定信息选项)。
option domain-name"example.org"; #具体的DNS服务器 option domain-name-servers ns1.example.org, ns2.example.org; #默认租约为600s default-lease-time600; #最大租约为7200s,客户机会在default-lease-time快到期时向服务器续租,如果此时客户机死机/重启,而默认租约时间到期了,服务器并不会立即回收IP地址,...
it is usual that some network element along the way acting as a DHCP relay stuffs a so-called ‘relay agent information option’ aka “option 82” into the DHCPDISCOVER packets. This option has several suboptions: “Agent Circuit ID” and “Agent Remote ID”. One of those two usually uni...

我遇到这个问题,以为是在用户层代码,通过DHCP接口发送discover包,其中增加option60段,内容填充huawei:hilink:gateway即可,这个思想是错误的,方向性错误。应该是修改系统dhcp设置即可。 大部分人,包括我自己只知道dhcp是获取ip的,但是对dhcp的整个过程不是太了解,所以改变字段更是无从下手。
