（八）VRRP原理

1.ARRP（网关冗余技术）

2.MSTP防止环路，VRRP主备切换

（九）VRRP配置

1，配置接入交换机acsw

system-view

sysname acsw

interface gigabitethernet 0/0/3

vlan 10

port link-type access //access接口

port default vlan 10

quit

interface gigabitethernet 0/0/1 //trunk 接口

port link-type trunk

port trunk allow-pass vlan all

interface gigabitethernet 0/0/2

port link-type trunk

port trunk allow-pass vlan all

quit

2.配置核心交换机coresw1

system-view

sysname coresw1

interface gigabitethernet 0/0/1

port link-type trunk

port trunk allow-pass vlan all

interface gigabitethernet 0/0/3

port link-type trunk

port trunk allow-pass vlan all

quit

vlan batch 10 100

interface gigabitethernet 0/0/2

port link-type access

port default vlan 100

quit

interface vlanif 10 

ip address 192.168.10.252 24

quit

interface vlanif 100

ip address 192.168.100.1 30

quit

interface vlanif 10

vrrp vrid 10 virtual-ip 192.168.10.254 //给备份组配置虚拟IP地址

vrrp vrid 10 priority 120 //配置优先级

vrrp vrid 10 preempt-mode timer delay 20  配置备份组中设备的抢占延迟时间

quit

ip route-static 0.0.0.0 0 192.168.100.2 //配置默认路由

interface vlanif 10

vrrp vrid 10 track interface gigabitethernet 0/0/2 reduced 30 //监视接口

quit

3.配置核心交换机coresw2

system-view

 sysname coresw2

interface gigabitethernet 0/0/1

port link-type trunk

port trunk allow-pass vlan all

quit

interface gigabitethernet 0/0/3

port link-type trunk

port trunk allow-pass vlan all

quit

vlan batch 10 200

interface gigabitethernet 0/0/2

port link-type access

port default valn 200

quit

interface vlanif 10

ip address 192.168.10.253 24

quit

interface vlanif 200

ip address 192.168.200.1 30

quit

interface vlanif 10

vrrp vrid 10 virtual-ip 192.168.10.254

quit

ip route-static 0.0.0.0 0 192.168.200.2 //配置默认路由

4.配置路由器AR1

system-view

sysname AR1

interface gigabitethernet 0/0/1

ip address 192.168.100.2 30

interface gigabitethernet 0/0/0

ip address 100.1.1.2 30

interface gigabitethernet 0/0/2

ip address 192.168.200.2 30

quit

ip route-static 192.168.10.0 24 192.168.100.1

ip route-static 192.168.10.0 24 192.168.100.2

5.配置互联网

ip route-static 192.168.10.0 24  100.1.1.2 //静态路由
