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

配置交换机

配置PC

汇聚到核心层路由配置
SW1-SW2：VLAN 102---10.10.2.0/24

SW1-SW3：VLAN 103---10.10.3.0/24

SW1-SW4：VLAN 104---10.10.4.0/24

SW2-SW3：VLAN 203---10.20.3.0/24

SW2-SW4：VLAN 204---10.20.4.0/24

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

ip vpn-instance VRF //创建VRF空间

route-distinguisher 100:1 //设定RD值

vpn-target 100:1 both //设定RT值

ip binding vpn-instance VRF //将接口划入到VRF这个交换机中，在接口进行配置之前执行

在进行配置时，需要携带vpn-instance参数，创建Vlanif接口，并将接口划入VRF空间：

[SW1]interface Vlanif 102
[SW1-Vlanif102]ip binding vpn-instance VRF //将接口划入到VRF这个交换机中，在接口进行配置之前执行
[SW1-Vlanif102]ip address 10.10.2.1 24

[SW1]interface Vlanif 103
[SW1-Vlanif103]ip binding vpn-instance VRF
[SW1-Vlanif103]ip add 10.10.3.1 24

[SW1]interface Vlanif 104
[SW1-Vlanif104]ip binding vpn-instance VRF
[SW1-Vlanif104]ip add 10.10.4.1 24

[SW2]interface Vlanif 102
[SW2-Vlanif102]ip binding vpn-instance VRF
[SW2-Vlanif102]ip address 10.10.2.2 24

[SW2]interface Vlanif 203
[SW2-Vlanif203]ip binding vpn-instance VRF
[SW2-Vlanif203]ip address 10.20.3.2 24

[SW2]interface Vlanif 204
[SW2-Vlanif204]ip binding vpn-instance VRF
[SW2-Vlanif204]ip add 10.20.4.2 24

配置OSPF

配置路由策略

删除宣告的192.168.2.0/24和192.168.3.0/24网段信息，防止发生冲突

VRF交换机和防火墙的路由交互
