实验步骤：

1. 按照拓扑图连接以及配置IP地址

根据拓扑图，将设备连接好，配置各个设备的IP地址。具体配置如下：

PC1: 192.168.1.1/24
PC2: 192.168.1.2/24
PC3: 192.168.2.1/24
PC4: 192.168.2.2/24
PC5: 192.168.3.1/24
PC6: 192.168.3.2/24
PC7: 192.168.4.2/24

SW1:
    VLAN10: 192.168.1.254/24
    VLAN20: 192.168.3.254/24
    VLAN30: 192.168.5.254/24
    VLAN40: 192.168.7.254/24

SW2:
    VLAN10: 192.168.1.253/24
    VLAN20: 192.168.3.253/24
    VLAN30: 192.168.5.253/24
    VLAN40: 192.168.7.253/24

SW3:
    VLAN10: 192.168.2.254/24
    VLAN20: 192.168.3.1/24
    VLAN30: 192.168.6.254/24
    VLAN40: 192.168.8.254/24

SW4:
    VLAN10: 192.168.2.253/24
    VLAN20: 192.168.3.2/24
    VLAN30: 192.168.6.253/24
    VLAN40: 192.168.8.253/24

2. 所有端口配置trunk放行vlan

将所有设备的端口都配置为trunk，并放行所需要的VLAN。具体配置如下：

SW1:
    interface range GigabitEthernet 0/1-2
        switchport mode trunk
        switchport trunk allowed vlan 10,20,30,40

SW2:
    interface range GigabitEthernet 0/1-2
        switchport mode trunk
        switchport trunk allowed vlan 10,20,30,40

SW3:
    interface range GigabitEthernet 0/1-2
        switchport mode trunk
        switchport trunk allowed vlan 10,20,30,40

SW4:
    interface range GigabitEthernet 0/1-2
        switchport mode trunk
        switchport trunk allowed vlan 10,20,30,40

3. 使用VRRP. PC6的主网关为sw1，pc7的主网关为sw3

在SW1和SW3上分别配置VRRP，将PC6和PC7的主网关设置为VRRP虚拟IP地址。具体配置如下：

SW1:
    interface vlan 10
        ip address 192.168.1.254/24
        vrrp 1 ip 192.168.1.1
        vrrp 1 priority 100
        vrrp 1 preempt

    interface vlan 20
        ip address 192.168.3.254/24
        vrrp 2 ip 192.168.3.1
        vrrp 2 priority 100
        vrrp 2 preempt

SW3:
    interface vlan 20
        ip address 192.168.3.1/24
        vrrp 2 ip 192.168.3.1
        vrrp 2 priority 100
        vrrp 2 preempt

    interface vlan 30
        ip address 192.168.6.254/24
        vrrp 3 ip 192.168.6.1
        vrrp 3 priority 100
        vrrp 3 preempt

4. 要求sw1和sw2互为主备，当设备故障时能够切换

在SW1和SW2上分别配置VRRP，将VLAN10和VLAN20设置为主备关系。具体配置如下：

SW1:
    interface vlan 10
        ip address 192.168.1.254/24
        vrrp 1 ip 192.168.1.1
        vrrp 1 priority 100
        vrrp 1 preempt

    interface vlan 20
        ip address 192.168.3.254/24
        vrrp 2 ip 192.168.3.1
        vrrp 2 priority 100
        vrrp 2 preempt

SW2:
    interface vlan 10
        ip address 192.168.1.253/24
        vrrp 1 ip 192.168.1.1
        vrrp 1 priority 90
        vrrp 1 preempt

    interface vlan 20
        ip address 192.168.3.253/24
        vrrp 2 ip 192.168.3.1
        vrrp 2 priority 90
        vrrp 2 preempt

5. 要求业务流量能和sw1的公关流量互访

为了使业务流量能够和SW1的公关流量互访，需要在SW1上添加路由。具体配置如下：

SW1:
    ip route 0.0.0.0 0.0.0.0 192.168.7.253

至此，新华三模拟器VRRP实验完成。
