本知识重点考核大家对VRRP、DHCP掌握情况，实验要求如下：
     实验要求：
    1.SW1为vlan 10的主网关，vlan 20的备份网关；
    2.SW2为vlan 20的主网关，vlan 10的备份网关；
    3.DHCP服务器在vlan 66，网关在SW2上面；
    4.PC1、PC2自动获取ip地址且可以互相ping通。

*  实验拓扑图如下：

第一步，进行基本网络配置，配置步骤及命令如下：

SW1上配置如下命令：

sysname SW1  
vlan batch 10 20 66  
interface GigabitEthernet0/0/1  
port link-type access  
port default vlan 10  
interface GigabitEthernet0/0/2  
port link-type trunk  
port trunk allow-pass vlan all  
interface Vlanif10  
ip address 192.168.10.251 255.255.255.0  
interface Vlanif20  
ip address 192.168.20.251 255.255.255.0  
interface Vlanif66  
ip address 192.168.66.251 255.255.255.0

SW2上配置如下命令：

sysname SW2  
vlan batch 10 20 66  
interface GigabitEthernet0/0/1  
port link-type access  
port default vlan 20  
interface GigabitEthernet0/0/2  
port link-type trunk  
port trunk allow-pass vlan all  
interface GigabitEthernet0/0/3  
port link-type access  
port default vlan 66  
interface Vlanif10  
ip address 192.168.10.252 255.255.255.0  
interface Vlanif20  
ip address 192.168.20.252 255.255.255.0  
interface Vlanif66  
ip address 192.168.66.252 255.255.255.0

第二步，进行VRRP配置，如下：
       SW1上配置如下命令：

interface Vlanif10  
vrrp vrid 10 virtual-ip 192.168.10.250  
vrrp vrid 10 priority 200  
interface Vlanif20  
vrrp vrid 20 virtual-ip 192.168.20.250

SW2上配置如下命令：

interface Vlanif10  
vrrp vrid 10 virtual-ip 192.168.10.250  
interface Vlanif20  
vrrp vrid 20 virtual-ip 192.168.20.250  
vrrp vrid 20 priority 200

第三步，配置DHCP，命令如下：
    
    DHCP服务器配置

sysname DHCP  
interface GigabitEthernet0/0/0  
ip address 192.168.66.1 255.255.255.0  
dhcp select global  
ip route-static 0.0.0.0 0.0.0.0 192.168.66.252  
ip pool p1  
gateway-list 192.168.10.250  
network 192.168.10.0 mask 255.255.255.0  
dns-list 8.8.8.8  
ip pool p2  
gateway-list 192.168.20.250  
network 192.168.20.0 mask 255.255.255.0  
dns-list 8.8.8.8

SW1上配置如下命令：

dhcp enable  
interface Vlanif10  
dhcp select relay  
dhcp relay server-ip 192.168.66.1  
interface Vlanif20  
dhcp select relay  
dhcp relay server-ip 192.168.66.1

SW1上配置如下命令：

dhcp enable  
interface Vlanif10  
dhcp select relay  
dhcp relay server-ip 192.168.66.1  
interface Vlanif20  
dhcp select relay  
dhcp relay server-ip 192.168.66.1

最后，进行验证查看。
        查看vrrp如下：

PC端查看如下：

通过以上查看得知，网关以及DHCP配置均满足实验要求，实验完成！！！
