描述
在路由器或交换机上配置动态主机配置协议 （DHCP） 本地服务器选项，以使路由器或交换机能够用作扩展 DHCP 本地服务器。DHCP 本地服务器从 DHCP 客户端接收 DHCP 请求和回复数据包，然后使用 IP 地址和其他可选配置信息向客户端进行响应。
扩展 DHCP 本地服务器与 J 系列路由器上的 DHCP 服务器不兼容，因此在 J 系列路由器上不受支持。此外，在层次结构级别下 [edit forwarding-options helpers] 配置的 DHCP 本地服务器和 DHCP/BOOTP 中继服务器不能同时在路由器或交换机上启用。扩展 DHCP 本地服务器与扩展 DHCP 中继功能完全兼容。
该 dhcpv6 节将路由器或交换机配置为支持 IPv6 动态主机配置协议 （DHCPv6）。DHCPv6 本地服务器与扩展 DHCP 本地服务器和扩展 DHCP 中继功能完全兼容。
注意：
在路由实例层次结构级别配置 dhcp-local-server 语句时，必须使用路由实例类型 virtual-router。
其余语句将单独解释。有关详细信息，请在 CLI 资源管理器 中搜索语句，或单击语法部分中的链接语句。
