我正在尝试在 PT 上创建一个实验室，并附上了一张图片。但由于某种原因，我的 PC 无法从 DHCP 服务器获取 IP 地址。第 1 层和第 2 层没有问题。我检查了路由，这似乎也很好。任何帮助表示赞赏:)

开关配置：

interface FastEthernet0/1
 switchport access vlan 10
 switchport mode access
 switchport nonegotiate
!
interface FastEthernet0/2
 switchport access vlan 20
 switchport mode access
 switchport nonegotiate
!
interface FastEthernet0/3
 switchport trunk encapsulation dot1q
 switchport mode trunk
!

interface Vlan1
 no ip address
 shutdown
!
interface Vlan10
 mac-address 00e0.a341.0e01
 no ip address
!
interface Vlan20
 mac-address 00e0.a341.0e02
 no ip address

end

路由器配置：

interface GigabitEthernet0/0
 ip address 10.0.0.1 255.255.255.0
 duplex auto
 speed auto
!
interface GigabitEthernet0/0.10
 encapsulation dot1Q 10
 ip address 20.0.0.1 255.255.255.0
!
interface GigabitEthernet0/0.20
 encapsulation dot1Q 20
 ip address 30.0.0.1 255.255.255.0
 ip helper-address 30.0.0.1

interface Vlan1
 no ip address
 shutdown
