VRRP小练习_the virtual ip address is not within a subnet on t

 1.配置IP及改名（太简单省略）

2.SW1配置：

SW1：
<Huawei>u t m
<Huawei>sys
[Huawei]
[Huawei]sys SW1
[SW1]vlan bat 10 20 13
Info: This operation may take a few seconds. Please wait for a moment...done.
[SW1]vlan 10
[SW1-vlan10]q
[SW1]int v 10
[SW1-Vlanif10]ip add 192.168.10.251 24    #配置SW1  vlan10 IP
[SW1-Vlanif10]int v 20
[SW1-Vlanif20]ip add 192.168.20.251 24    #配置SW1的Vlan 20 IP
[SW1-Vlanif20]vrrp vrid 20 virt 192.168.20.254  #在vlan 20虚接口配置vrrp
[SW1-Vlanif20]vrrp vrid 10 virt 192.168.10.254  #证明无法在vlan 20上配置不在vlan 20 所属网段的虚拟ip地址
Error: The virtual IP address is not within a subnet on this interface.
[SW1-Vlanif20]int v 10
[SW1-Vlanif10]vrrp vrid 10 virt 192.168.10.254  #在vlan 10虚接口配置vrrp
[SW1-Vlanif10]vrrp vrid 10 pri 130        #设为master路由
[SW1-Vlanif10]vrrp vrid 10 track int g0/0/2 redu 100   #做上行接口跟踪

[SW1-Vlanif10]ip route	        #证明无法在虚接口视图下配置静态路由
[SW1-Vlanif10]q
[SW1]ip route-static 192.168.3.0 24 192.168.13.3
[SW1]int v 13

[SW1-GigabitEthernet0/0/2]q
[SW1]ip route-s 0.0.0.0 0 192.168.13.3    #拓扑图内还有2.0网段，省事情直接写默认路由

3.SW2配置：

SW2：
<Huawei>u t m
<Huawei>sys
[Huawei]sys SW@        #按错了
[SW@]sys SW2
[SW2]vlan bat 10 20
Info: This operation may take a few seconds. Please wait for a moment...done.
[SW2]int v 10
[SW2-Vlanif10]ip add 192.168.10.252 24    #设置vlan 10的ip地址
[SW2-Vlanif10]vrrp vrid 10 vir 192.168.10.254        #配置vlan 10的vrrp 由于SW2非10.0网段的master路由，故不配置优先级了
[SW2-Vlanif10]int v 20
[SW2-Vlanif20]ip add 192.168.20.252 24   #设置vlan 20的ip
[SW2-Vlanif20]vrrp vrid 20 vir 192.168.20.254        #配置vlan 20的vrrp
[SW2-Vlanif20]vrrp vrid 20 pri 130
[SW2-Vlanif20]vrrp vrid 20 track int g0/0/2 redu 100  #配置上行接口跟踪
[SW2-Vlanif20]q
[SW2]int g0/0/2
[SW2-GigabitEthernet0/0/2]p l a
[SW2-GigabitEthernet0/0/2]p d v 20
[SW2-GigabitEthernet0/0/2]int g 0/0/1

[SW2-GigabitEthernet0/0/1]p l t
[SW2-GigabitEthernet0/0/1]p t a v 20
[SW2-GigabitEthernet0/0/1]q
[SW2]ip route-s 192.168.3.0 24 192.168.23.3

[Huawei]ip route-s 192.168.0.0 16 192.168.23.1 pre 70

6.测试：

1）完好时测试

2）SW1故障测试

问题出在SW2的g0/0/1口

PC1带有vlan10标签的数据帧无法通过故要新加命令：

[SW2-GigabitEthernet0/0/1]p t a v 10

3）SW2故障测试：
