配置路由

现在PC1和3台交换机是通的,但是到不了互联网

[LSW3-GigabitEthernet0/0/2]q
[LSW3]

VRRP配置

VRRP虚拟ip:192.168.10.254

默认优先级100,所有LSW2是主,LSW3是备

[LSW3]
[LSW3]interface vlanif 10
[LSW3-Vlanif10]vrrp vrid 10 virtual-ip 192.168.10.254
[LSW3-Vlanif10]q
[LSW3]

配置默认路由

[LSW3]
[LSW3]ip route-static 0.0.0.0 0 192.168.200.2
[LSW3]

R1路由器配置

基础配置

ge0/0/1:192.168.100.2/30

ge0/0/2:192.168.200.2/30

ge0/0/0:100.1.1.2/30

<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname AR1
[AR1]interface gigabitethernet 0/0/1
[AR1-GigabitEthernet0/0/1]ip address 192.168.100.2 30
[AR1-GigabitEthernet0/0/1]q
[AR1]interface gigabitethernet 0/0/2
[AR1-GigabitEthernet0/0/2]ip address 192.168.200.2 30
[AR1-GigabitEthernet0/0/2]q
[AR1]interface gigabitethernet 0/0/0
[AR1-GigabitEthernet0/0/0]ip address 100.1.1.2 30
[AR1-GigabitEthernet0/0/0]q
[AR1]

路由配置

将10网段指向100.1、200.1

回去有两条路,LSW2路由器出现故障挂掉的还可以走右边。

[AR1]
[AR1]ip route-static 192.168.10.0 24 192.168.100.1
[AR1]ip route-static 192.168.10.0 24 192.168.200.1
[AR1]

R2路由器配置

基础配置

ge0/0/0:100.1.1.1/30

<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]undo info-center enable
Info: Information center is disabled.
[Huawei]sysname AR2
[AR2]interface gigabitethernet 0/0/0
[AR2-GigabitEthernet0/0/0]ip address 100.1.1.1 30
[AR2-GigabitEthernet0/0/0]q

路由配置

将10网段丢给100.1.1.2,不然10网段请求过来,返回不去

[AR2]ip route-static 192.168.10.0 24 100.1.1.2
[AR2]q
<AR2>

至此全部配置完成,这个拓扑主要练习VRRP和路由走向关系。可以用pc1在ping100.1.1.1时候抓包看默认走的左边还是右边。很明显左边是主默认走左边,当我们把LSW2的ge0/0/2端口shutdown掉或者关机还是把线路删掉,会自动走备路线往右边出去。当左边的LSW2交换机恢复正常后,需要等待20秒后才会回复成master
