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。<?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" />

目标  网络规划如下:交换机之间的接口全部为trunk模式。

sw1sw2上配置hsrp,活跃交换机优先级为150.备份交换机优先级为100.

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

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

PCip地址及网关如下:

u      Pc1ip地址:192.168.2.10/24,网关为192.168.2.254/24

u      Pc2ip地址:192.168.3.10/24,网关为192.168.3.254/24

u      Pc3ip地址:192.168.2.11/24,网关为192.168.2.254/24

u      Pc4ip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vlan2vlan34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VlanIp地址

Hsrp:各个Vlan的虚拟网关,优先级和占先权。

4STp实现负载均衡

sw2(config-if)#standby 2 track loopback 0 100

sw2(config)#int vlan 3

sw2(config-if)#standby 3 track loopback 0 100

sw2(config-if)#exit

sw2(config)#int vlan 4

sw2(config-if)#standby 4 track loopback 0 100

SW 1:断开跟踪端口
