dhcp option82

DHCP option 82，也称为DHCP中继代理信息选项（Relay Agent Information Option），是DHCP报文中的一个选项，其编号为82。它用于在DHCP请求报文中传递关于DHCP中继代理的信息。当DHCP客户端发送请求报文到DHCP服务器时，如果需要经过DHCP中继代理，则DHCP中继代理会将option 82添加到请求报文中。Option 82包含多个子选项，其中sub-option 1定义了代理电路ID（即circuit id），sub-option 2定义了代理远程ID（即remote id），sub-option 5为链路选择（link selection）子项，该选项中包含了DHCP中继代理添加的IP地址。\[1\]\[2\]\[3\]
