我这里有一个H3C网络拓扑，请帮我配置： 两台核心交换机互联，下面单独连两台汇聚交换机，汇聚交换机也互联，两台汇聚交换机向下连同一台接入交换机，接入交换机下面连两台pc。配置要求：做DHCP，VRRP,MSTP，合理规划

好的，以下是基本的 H3C 网络拓扑配置：

首先，我们需要为核心交换机配置 VRRP。假设两台核心交换机的 IP 地址为 192.168.1.1 和 192.168.1.2，VRRP 虚拟 IP 地址为 192.168.1.100，VRRP 虚拟 MAC 地址为 0000-5e00-0101。

1. 配置 VRRP 路由器 ID：

[SW1] vrrp vrid 1 virtual-router-id 1
[SW1-vrrp-vrid-1] quit

[SW2] vrrp vrid 1 virtual-router-id 1
[SW2-vrrp-vrid-1] quit

2. 配置 VRRP 接口：

[SW1] interface GigabitEthernet1/0/1
[SW1-GigabitEthernet1/0/1] vrrp vrid 1 virtual-ip 192.168.1.100
[SW1-GigabitEthernet1/0/1] quit

[SW2] interface GigabitEthernet1/0/1
[SW2-GigabitEthernet1/0/1] vrrp vrid 1 virtual-ip 192.168.1.100
[SW2-GigabitEthernet1/0/1] quit

3. 配置 MSTP：

[SW1] stp region-configuration
[SW1-stp-region] revision-level 1
[SW1-stp-region] instance 1 vlan 1 to 4094
[SW1-stp-region] instance 2 vlan 1 to 4094
[SW1-stp-region] instance 3 vlan 1 to 4094
[SW1-stp-region] quit

[SW2] stp region-configuration
[SW2-stp-region] revision-level 1
[SW2-stp-region] instance 1 vlan 1 to 4094
[SW2-stp-region] instance 2 vlan 1 to 4094
[SW2-stp-region] instance 3 vlan 1 to 4094
[SW2-stp-region] quit

4. 配置 DHCP：

[SW1] dhcp enable
[SW1] interface Vlanif1
[SW1-Vlanif1] ip address 192.168.1.254 24
[SW1-Vlanif1] dhcp select relay
[SW1-Vlanif1] dhcp relay server-select 1
[SW1-Vlanif1] quit

[SW2] dhcp enable
[SW2] interface Vlanif1
[SW2-Vlanif1] ip address 192.168.1.253 24
[SW2-Vlanif1] dhcp select relay
[SW2-Vlanif1] dhcp relay server-select 1
[SW2-Vlanif1] quit

[SW3] dhcp server group 1
[SW3-dhcp-server-1] gateway-list 192.168.1.254
[SW3-dhcp-server-1] network 192.168.2.0 mask 255.255.255.0
[SW3-dhcp-server-1] quit

5. 配置汇聚交换机：

[SW1] interface GigabitEthernet1/0/2
[SW1-GigabitEthernet1/0/2] stp edged-port enable
[SW1-GigabitEthernet1/0/2] port link-type trunk
[SW1-GigabitEthernet1/0/2] port trunk allow-pass vlan 10 to 20
[SW1-GigabitEthernet1/0/2] quit

[SW2] interface GigabitEthernet1/0/2
[SW2-GigabitEthernet1/0/2] stp edged-port enable
[SW2-GigabitEthernet1/0/2] port link-type trunk
[SW2-GigabitEthernet1/0/2] port trunk allow-pass vlan 10 to 20
[SW2-GigabitEthernet1/0/2] quit

6. 配置接入交换机：

[SW3] interface GigabitEthernet1/0/1
[SW3-GigabitEthernet1/0/1] port link-type access
[SW3-GigabitEthernet1/0/1] port default vlan 10
[SW3-GigabitEthernet1/0/1] quit

7. 配置 PC：

[PC1] ip address 192.168.2.2 255.255.255.0 192.168.2.1
[PC1] gateway 192.168.2.1

[PC2] ip address 192.168.2.3 255.255.255.0 192.168.2.1
[PC2] gateway 192.168.2.1

以上仅为基础配置，您还可以根据实际需求进行优化。
