华为vrrp配置
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
sysname sw1
创建vlan
vlan batch 10 20 30 40
加入vlan10
inter GigabitEthernet 0/0/1
port link-type access
port default vlan 10
加入vlan20
inter gi 0/0/2
port link-typeaccess
port default vlan 20
加入vlan30
inter gi 0/0/3
port link-type access
port default vlan 30
加入vlan40
inter gi0/0/4
port link-type access
port default vlan 40
q
配置trunk模式
inter GigabitEthernet 0/0/6
port link-typetrunk
port trunk allow-pass vlan all
inter gi 0/0/5
port link-type trunk
port trunk allow-pass vlan a
配置sw2
<Huawei>sys
创建vlan
vlan batch 10 20 30 40
每个vlan配置ip地址
inter vlan 10
ip address 192.168.10.253 255.255.255.0
inter vlan 20
ip address 192.168.20.253 255.255.255.0
inter vlan 30
ip address 192.168.30.253 255.255.255.0
inter vlan 40
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
vrrp vrid 40 virtual-ip 192.168.40.250
配置优先级
vrrp vrid 40 priority 150
配置 链路跟踪
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
inter vlan 30
vrrp vrid 30 virtual-ip 192.168.30.250
vrrp vrid 30 priority 100
vrrp vrid 30 track interface GigabitEthernet 0/0/2 reduced 100
开启vlan10的vrrp功能
inter vlan 10
vrrp vrid 10 virtual-ip 192.168.10.250
开启vlan20的vrrp功能
inter vlan 20
vrrp vrid 20 virtual-ip 192.168.20.250
将gi0/0/1配置为trunk模式
inter gi0/0/1
port link-type trunk
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
vlan batch 10 20 30 40
inter vlan 10
ip address 192.168.10.254 255.255.255.0
inter vlan 20
ip address 192.168.20.254 255.255.255.0
inter vlan 30
ip address 192.168.30.254 255.255.255.0
inter vlan 40
ip address 192.168.40.254 255.255.255.0
q
inte gi 0/0/1
port link-type trunk
port trunk allow-pass vlan all
q
inter vlan 10
vrrp vrid 10 virtual-ip 192.168.10.250
vrrp vrid 10 priority 150
vrrp vrid 10 track inter gi 0/0/2 reduced 100
inter vlan 20
vrrp vrid 20 virtual-ip 192.168.20.250
vrrp vrid 20 priority 150
vrrp vrid 20 track inter gi0/0/2 reduced 100
验证：实现全网通
开启 debug
<sw1>terminal monito
<sw1>terminal debugging
<sw1>debugging ip icmp
<sw1>sys
info-center console channel monitor
发包
回包看看是哪个三层
