实验名称：配置HSRP，实现网络的负载均衡
实验环境描述：随着公司的发展，公司对网络的要求也越来越高，为此公司决定搭建由两台核心交换机做热备的公司网络，如图，为了充分利用网络资源，公司还要求实现vlan的负载均衡。如图所示，搭建网络实现热备份和vlan的负载均衡。
目标  网络规划如下：交换机之间的接口全部为trunk模式。
在sw1和sw2上配置hsrp，活跃交换机优先级为150.备份交换机优先级为100.
在sw1交换机上配置vlan接口ip地址：
u      Vlan2接口的ip地址：192.168.2.1/24
u      Vlan3接口的ip地址：192.168.3.1/24
u      Vlan4接口的ip地址：192.168.4.1/24
在sw2交换机上配置vlan接口ip地址：
u      Vlan2接口的ip地址：192.168.2.2/24
u      Vlan3接口的ip地址：192.168.3.2/24
u      Vlan4接口的ip地址：192.168.4.2/24
PC的ip地址及网关如下：
u      Pc1的ip地址：192.168.2.10/24，网关为192.168.2.254/24
u      Pc2的ip地址：192.168.3.10/24，网关为192.168.3.254/24
u      Pc3的ip地址：192.168.2.11/24，网关为192.168.2.254/24
u      Pc4的ip地址：192.168.4.10/24，网关为192.168.4.254/24
 
需求描述
配置vlan负载均衡时，使用pvsf+并且要求vlan2和vlan3、4实现负载均衡。
交换机网络规划配置：
 
推荐步骤：
1：划分Vlan
2：各交换机都trunk
3：配各Vlan的Ip地址
配Hsrp：各个Vlan的虚拟网关，优先级和占先权。
4：STp实现负载均衡
