"Relay Agent IP Address" 是 DHCP 协议中的一个字段,它是由 DHCP Relay Agent 在 DHCP 报文中添加的。DHCP Relay Agent 是一种网络设备,它可以将 DHCP 报文从一个子网转发到另一个子网,以便客户端可以在不同的子网上获取 IP 地址。Relay Agent IP Address 字段用于标识 DHCP Relay Agent 的 IP 地址,以便 DHCP 服务器可以确定客户端所在的子网。

DHCP报文中,服务器分配给客户端的IP地址会写入哪个字段? A Next Server IP address B Your IP address C Client IP address D Relay agent IP address
DHCP报文中,服务器分配给客户端的IP地址会写入Your IP address字段中。在DHCP协议中,客户端通过DHCP discover报文发现DHCP服务器,然后向DHCP服务器发送DHCP request报文请求租用IP地址。DHCP服务器在收到请求后,向客户端发送DHCP offer报文,其中包含可用的IP地址租用地址。客户端在收到DHCP offer报文后,向DHCP服务器发送DHCP request报文确认租约。DHCP服务器在收到确认请求后,向客户端发送DHCP ack报文确认租约,并将租用信息发送给客户端。其中包括分配给客户端的IP地址,这个IP地址会写入Your IP address字段中。因此,答案是B。
dhcp relay server-ip
DHCP relay agent is used to forward DHCP messages from one network segment to another. When a DHCP client broadcasts a DHCP discovery message to find a DHCP server, the message is not forwarded across different network segments by default. The DHCP relay agent receives the DHCP discovery message and forwards it to one or more DHCP servers on different network segments.
The server-ip parameter is used to specify the IP address of the DHCP server to which the DHCP relay agent forwards the DHCP messages. This parameter is used in the configuration of the DHCP relay agent to specify the IP address of the DHCP server to which the client requests should be forwarded.
