一、实验拓扑图如下
二、实验简介
从拓扑可以看到，我是利用两个华为S5700作为主备核心，在其上建立vlan 20和30 作为业务vlan，建立vlan100 作为心跳vlan；利用华为S3700作为接入交换机，直接和PC相连，在S3700上建立Vlan20和Vlan30等业务vlan。
三、具体规划配置如下
在S5700-Master规划如下：
1、创建vlan 10
interface vlanif 10 ：192.168.10.1 24
Virtual IP : 192.168.10.254
2、创建vlan 20
interface vlanif 20：192.168.20.1 24
Virtual IP : 192.168.20.254
3、创建vlan 100
interface vlanif 100：100.100.100.1 24
4、创建interface Eth-Trunk 1，并配置为Trunk，只允许vlan100通过，将GE0/0/1和GE0/0/2端口加入到Eth-Trunk1中。
5、配置GE0/0/3和GE0/0/4的端口类型为Trunk端口，为了精确只允许业务Vlan通过
在S5700-Backup规划如下：
1、创建vlan 10
interface vlanif 10 ：192.168.10.2 24
Virtual IP : 192.168.10.254
2、创建vlan 20
interface vlanif 20：192.168.20.2 24
Virtual IP : 192.168.20.254
3、创建vlan 100
interface vlanif 100：100.100.100.2 24
4、创建interface Eth-Trunk 1，并配置为Trunk，只允许vlan100通过，将GE0/0/1和GE0/0/2端口加入到Eth-Trunk1中。
5、配置GE0/0/3和GE0/0/4的端口类型为Trunk端口，为了精确，只允许业务Vlan通过。
备注：1、在S5700交换机与S3700交换机相连的端口上开启STP，其模式是MSTP，默认的情况下华为交换机是开启的，如果没有开启，请手动开启；
S3700A配置规划如下：
1、创建vlan 10 20 ；
2、将Ethernet0/0/3和Ethernet0/0/4的端口类型为Trunk，只要允许业务vlan10 和vlan20 通过即可；
S3700B配置规划如下：
1、创建vlan 10 20 ；
2、将Ethernet0/0/3和Ethernet0/0/4的端口类型为Trunk，只要允许业务vlan10 和vlan20 通过即可；
