双机热备旁挂组网场景实验

实验要求：

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、实验配置

1.二层交换机配置

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；

vlan	设备	ip	vlan虚拟ip
vlan2	sw3	192.168.2.1/24	192.168.2.254/24

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GE0/0/2、5、6、7属于该空间接口。

ospf：

此时回程流量是等价路由，负载均衡，不符合来回路径一致要求。故需要进行路由干涉，使用路由策略。
sw3和sw4只需要修改接口Cost数值，让sw3优选从SW1学习到的路由，让sw4优先从sw2学习到的路由即可。

路由策略规划：
sw3：
主要流量发送给sw1，备份发给sw2
sw4：
主要流量发送给sw2，备份发给sw1
sw1：
192.168.2.0/24----> 主要流量发送给sw3，备份发给sw4
192.168.3.0/24----> 主要流量发送给sw4，备份发给sw3
sw2：
192.168.2.0/24----> 主要流量发送给sw3，备份发给sw4
192.168.3.0/24----> 主要流量发送给sw4，备份发给sw3

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：

[SW4-ospf-1-area-0.0.0.0]undo network 192.168.3.2 0.0.0.0

sw3
将sw3本地发送的192.168.3.0/24路由的开销值改大，192.168.2.0/24路由开销值不变。
通过重发布调用路由策略：重发布时不要引入其他路由信息。
1、抓流量
[SW3]ip ip-prefix aa permit 192.168.2.0 24
[SW3]ip ip-prefix bb permit 192.168.3.0 24
2、做策略
[SW3]route-policy bb permit node 10
[SW3-route-policy]if-match ip-prefix bb
[SW3-route-policy]apply cost 5
[SW3]route-policy bb permit node 20
[SW3-route-policy]if-match ip-prefix aa
3、调用策略
[SW3]ospf 1
[SW3-ospf-1]import-route direct route-policy bb

sw4
将sw4本地发送的192.168.2.0/24路由的开销值改大，192.168.3.0/24路由开销值不变。
通过重发布调用路由策略：重发布时不要引入其他路由信息。

引入静态路由：

[SW1-ospf-2]import-route static
[SW2-ospf-2]import-route static

四、试验检测
1.PC1和PC2分别pingISP的环回接口：

2.关闭SW1的某些接口后pingISP的环回接口：

[SW1-GigabitEthernet0/0/2]shutdown

（测试网络只存在一瞬间的丢弃，但网络并未断开）
