实验需求

① 该公司有市场部和技术部，分别划在VLAN 10 和 VLAN 20里面

② 此时为了网络的稳定性，需要在三层交换机上面做网关冗余技术（VRRP），要求LSW1作为PC1的主网关，PC2的备网关，LSW2作为PC2的主网关，PC1的备网关

③ 该公司的因特网出口 AR1 与两个汇聚交换机之间，采用三层方式互联，就是可以进行通信。

（这边可以注意一下：交换机要与路由器相连，让两边端口都能通信，有两种办法

进入交换机的接口，配置模式下undo switchport（模拟器一般不支持，真机支持）
用SVI接口，将交换机与路由器相连的端口设置为access端口，就OK了）

④ 然后在路由器AR1和两个汇聚交换机之间运行 OSPF，实现全互联

最终目的：
让PC1和PC2上网

LSW 3

接入层的配置，只需要将端口划分一下

LSW 1

基础配置

<Huawei>system-view     ## 进入配置视图
Enter system view, return user view with Ctrl+Z.  ## Ctrl+z可以回退到用户视图[Huawei]undo info-center enable           ##关闭系统自动弹出消息

[LSW1-GigabitEthernet0/0/2] port link-type trunk
[LSW1-GigabitEthernet0/0/2] port trunk allow-pass vlan all
[LSW1-GigabitEthernet0/0/2]quit ## 这个时候交换机与路由器互联的接口就用SVI接口来配置
[LSW1]int g0/0/1	
[LSW1-GigabitEthernet0/0/1]port link-type access    ## 将端口划分为access模式
[LSW1-GigabitEthernet0/0/1]port default vlan 100    ## 与VLAN 100 进行绑定
[LSW1-GigabitEthernet0/0/1]quit ## SVI接口
[LSW1]int vlan 100	
[LSW1-Vlanif100]ip address 192.168.1.2 24
[LSW1-Vlanif100]quit

VRRP

[LSW1]interface Vlan10    ##进入SVI10接口
[LSW1-Vlanif10] ip address 192.168.10.251 255.255.255.0    ## 配置IP地址
## 创建vrrp组10，虚拟ip为192.168.10.254
[LSW1-Vlanif10] vrrp vrid 10 virtual-ip 192.168.10.254     
## 修改优先级为120，作为VLAN 10的主网关，默认优先级是100
[LSW1-Vlanif10] vrrp vrid 10 priority 120                  
## 抢占延时为10秒，比如说我master坏了，我的backup变为master
## 那等我master修复好了，需要再等10s才能变为master
[LSW1-Vlanif10] vrrp vrid 10 preempt-mode timer delay 10   
## 配置VRRP备份组监视接口,如果我g0/0/1的接口down了，优先级就会减30
## 这个时候就会走backup那边
[LSW1-Vlanif10]vrrp vrid 10 track interface g0/0/1 reduced 30    
[LSW1-Vlanif10]quit[LSW1]interface Vlan20

[LSW1-Vlanif20] vrrp vrid 20 track interface g0/0/1 reduced 30   
[LSW1-Vlanif20]quit

DHCP

全局下的DHCP，才能去指定我的默认网关是192.168.10.254
如果是接口下的DHCP，它的默认网关是该接口，比如说VLAN10的网关就变成了192.168.10.252了，那就与我们的VRRP的冲突了，所以我们选择是全局下的DHCP

[LSW1]dhcp enable   ## 开启DHCP功能
Info: The operation may take a few seconds. Please wait for a moment.done.## 创建地址池vlan10 和 vlan20
[LSW1]ip pool vlan10

[LSW1-Vlanif10]quit[LSW1]int vlan 20	
[LSW1-Vlanif20]dhcp select global 
[LSW1-Vlanif20]quit

OSPF

## 进入OSPF进程110，RID手动改为2.2.2.2
[LSW1]ospf 110 router-id 2.2.2.2	
[LSW1-ospf-110]area 0	            ## 进入骨干区域
[LSW1-ospf-110-area-0.0.0.0]network 192.168.1.0 0.0.0.255   ## 宣告路由信息
[LSW1-ospf-110-area-0.0.0.0]network 192.168.10.0 0.0.0.255
[LSW1-ospf-110-area-0.0.0.0]network 192.168.20.0 0.0.0.255
[LSW1-ospf-110-area-0.0.0.0]quit 
[LSW1-ospf-110]qu

默认路由

这个一定要写的，因为PC要上网
把流量发到网关的时候，它找不到相对应的路由条目，就会导致通信失败
这个时候就需要再写一条默认路由，来指向全部IP地址，把流量丢给出口路由器AR1

[LSW1]ip route-static 0.0.0.0 0 192.168.1.1

当LSW1的G0/0/1接口down了，这个时候VLAN10的主网关就要变成了LSW2身上了

LSW1身上查看，都变成了backup
