双机热备旁挂组网实验

一、实验拓扑

二、实验需求

1、SW3的流量
正常情况下：SW1_VRF-->FW1--->SW1_Public--->R5
故障情况下：SW2_VRF-->FW2--->SW2_Public--->R6
2、SW4的流量
正常情况下：SW2_VRF-->FW2--->SW2_Public--->R6
故障情况下：SW1_VRF-->FW1--->SW1_Public--->R5
3、交换网络负载均衡

三、操作过程

1、二层交换配置

使用传统三层架构中MSTP+VRRP组网形式
        VLAN 2--->SW3,SW4作为备份
        VLAN 3--->SW4,SW3作为备份

MSTP设计--->SW3、4、5运行
        实例1：VLAN 2  
        实例2：VLAN 3
                SW3是实例1的主根，实例2的备份根；SW4是实例2的主根，实例1的备份根

IP地址规划：
SW3：
        VLAN 2:192.168.2.1/24
        VLAN 3:192.168.3.1/24
SW4：
        VLAN 2:192.168.2.2/24
        VLAN 3:192.168.3.2/24

虚拟IP：
        VLAN 2:192.168.2.254/24
        VLAN 3:192.168.3.254/24

创建VRF空间并配置VRF信息

        因为SW1和SW2需要被分割为两台设备，分别与上下行设备连接，故需要先创建VRF空间，其中GE0/0/3-GE0/0/6属于该空间接口。

VRF空间配置信息：
名称：VRF
RD：100:1
RT：100:1

[SW1]ip vpn-instance VRF          
[SW1-vpn-instance-VRF]route-distinguisher 100:1      
[SW1-vpn-instance-VRF-af-ipv4]vpn-target 100:1 both

Enter system view, return user view with Ctrl+Z.
