实验名称：华为vrrp配置
实验目的：为了实现路由器的冗余即备份，当其中一个三层交换机坏了，PC还能正常上网
实验拓扑：
SW3 配置步骤
思路：创建vlan10 20 30 40 ，01、02、03、04端口分别加入vlan10到40.
05、06端口配置trunk模式允许所有vlan通过
[Huawei]sysname sw1
创建vlan
[sw1]vlan batch 10 20 30 40
加入vlan10
[sw1]inter GigabitEthernet 0/0/1
[sw1-GigabitEthernet0/0/1]port link-type access
[sw1-GigabitEthernet0/0/1]port default vlan 10
加入vlan20
[sw1-GigabitEthernet0/0/1]inter gi 0/0/2
[sw1-GigabitEthernet0/0/2]port link-type access
[sw1-GigabitEthernet0/0/2]port default vlan 20
加入vlan30
[sw1-GigabitEthernet0/0/2]inter gi 0/0/3
[sw1-GigabitEthernet0/0/3]port link-type access
[sw1-GigabitEthernet0/0/3]port default vlan 30
加入vlan40
[sw1-GigabitEthernet0/0/3]inter gi0/0/4
[sw1-GigabitEthernet0/0/4]port link-type access
[sw1-GigabitEthernet0/0/4]port default vlan 40
[sw1-GigabitEthernet0/0/4]q
配置trunk模式
[sw1]inter GigabitEthernet 0/0/6
[sw1-GigabitEthernet0/0/6]port link-type trunk
[sw1-GigabitEthernet0/0/6]port trunk allow-pass vlan all
[sw1]inter gi 0/0/5
[sw1-GigabitEthernet0/0/5]port link-type trunk
[sw1-GigabitEthernet0/0/5]port trunk allow-pass vlan a
配置sw2
<Huawei>sys
创建vlan
[Huawei]vlan batch 10 20 30 40
每个vlan配置ip地址
[Huawei]inter vlan 10
[Huawei-Vlanif10]ip address 192.168.10.253 255.255.255.0
[Huawei-Vlanif10]inter vlan 20
[Huawei-Vlanif20]ip address 192.168.20.253 255.255.255.0
[Huawei-Vlanif20]inter vlan 30
[Huawei-Vlanif30]ip address 192.168.30.253 255.255.255.0
[Huawei-Vlanif30]inter vlan 40
[Huawei-Vlanif40]ip address 192.168.40.253 255.255.255.0
把vlan40加入组，并配置vrrp
vrrp配置虚拟IP
[Huawei-Vlanif40]vrrp vrid 40 virtual-ip 192.168.40.250
配置优先级
[Huawei-Vlanif40]vrrp vrid 40 priority 150
配置 链路跟踪
[Huawei-Vlanif40]vrrp vrid 40 track interface gi0/0/2 reduced 100（如果gi0/0/2端口的状态变为down，则优先级降低100，变为50）
相同的操作配置vlan30
[Huawei-Vlanif40]inter vlan 30
[Huawei-Vlanif30]vrrp vrid 30 virtual-ip 192.168.30.250
[Huawei-Vlanif30]vrrp vrid 30 priority 100
[Huawei-Vlanif30]vrrp vrid 30 track interface GigabitEthernet 0/0/2 reduced 100
开启vlan10的vrrp功能
[Huawei-Vlanif30]inter vlan 10
[Huawei-Vlanif10]vrrp vrid 10 virtual-ip 192.168.10.250
开启vlan20的vrrp功能
[Huawei-Vlanif10]inter vlan 20
[Huawei-Vlanif20]vrrp vrid 20 virtual-ip 192.168.20.250
将gi0/0/1配置为trunk模式
[Huawei-Vlanif20]inter gi0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan all
sw1
配置vlan10 20 的vrrp优先级为150
vlan30 40 开启vrrp
<Huawei>
<Huawei>sys
[Huawei]vlan batch 10 20 30 40
[Huawei]inter vlan 10
[Huawei-Vlanif10]ip address 192.168.10.254 255.255.255.0
[Huawei-Vlanif10]inter vlan 20
[Huawei-Vlanif20]ip address 192.168.20.254 255.255.255.0
[Huawei-Vlanif20]inter vlan 30
[Huawei-Vlanif30]ip address 192.168.30.254 255.255.255.0
[Huawei-Vlanif30]inter vlan 40
[Huawei-Vlanif40]ip address 192.168.40.254 255.255.255.0
[Huawei-Vlanif40]q
[Huawei]inte gi 0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[Huawei-GigabitEthernet0/0/1]q
[Huawei]inter vlan 10
[Huawei-Vlanif10]vrrp vrid 10 virtual-ip 192.168.10.250
[Huawei-Vlanif10]vrrp vrid 10 priority 150
[Huawei-Vlanif10]vrrp vrid 10 track inter gi 0/0/2 reduced 100
[Huawei-Vlanif10]inter vlan 20
[Huawei-Vlanif20]vrrp vrid 20 virtual-ip 192.168.20.250
[Huawei-Vlanif20]vrrp vrid 20 priority 150
[Huawei-Vlanif20]vrrp vrid 20 track inter gi0/0/2 reduced 100
验证：实现全网通
开启 debug
