实验内网无法获取请求前辈给予排错思路！

实验！

实验要求：

实验需求:
1.SW1 SW2 二层 SW3 三层
2.PC配置DHCP获取固定IP、PC3不能pingPC4但PC4可以pingPC3，其他都可以通
3.R1 单臂 R2 R3 SW3 GW OSPF 进程10 区域0 vlan都能通。
4.GW配置DHCP给PC分配 、NAT在vlan10和30访问internet 、vlan20和40 不能访问internet  
5.telnet 服务器映射23端口到internet的100.1.1.1:10000.在internet上通过命令 telnet 100.1.1.1:10000来远程telnet服务器


目前遇到的问题：
我的PC6和PC7 无法获取到DHCP固定IP分配，我在R2已经做路由协议 OSPF和静态宣告 192.168.50.254 查看路由表是有学习到的。
但SW3三层交换我尝试静态和宣告中继模式都无法Ping通过DHCP下发的地址池~请前辈给予我排错和配置思路学习，谢谢大佬。
以下是我的配置请前辈查验：
