VRRP实验

拓扑图

要求:

1、PC1和PC2处于不同的VLAN

2、SW1和SW2是终端设备的网关所在地

3、SW1作为VLAN 10的主网关；SW2作为VLAN 20的主网关

4、实现负载分担效果，且SW1和SW2互为备份

分析:

1.先规划好实验配置并写入拓扑图中

2.PC1划分为VLAN10,PC2划分为VLAN20,对各设备进行VLAN配置

3.对SW1和SW2进行VRRP配置

搭建:

1.VLAN配置

//SW3
[sw3]vlan batch 10 20
[sw3]int g0/0/1
[sw3-GigabitEthernet0/0/1]port link-type access 
[sw3-GigabitEthernet0/0/1]port default vlan 10
[sw3-GigabitEthernet0/0/1]int g0/0/2
[sw3-GigabitEthernet0/0/2]port link-type access
[sw3-GigabitEthernet0/0/2]port default vlan 20

//SW1
[sw1]vlan batch 10 20
[sw1]int g0/0/2
[sw1-GigabitEthernet0/0/2]port link-type trunk 
[sw1-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 20
[sw1]int g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk 
[sw1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20

//SW2
[sw2]vlan batch 10 20
[sw2]vlan batch 10 20
[sw2]int g0/0/2
[sw2-GigabitEthernet0/0/2]port link-type trunk 
[sw2-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 20
[sw2]int g0/0/1
[sw2-GigabitEthernet0/0/1]port link-type trunk 
[sw2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20

2.VRRP配置

//SW1
[sw1]int Vlanif 10
[sw1-Vlanif10]ip add 192.168.1.253 24
[sw1-Vlanif10]vrrp vrid 1 virtual-ip 192.168.1.254
[sw1-Vlanif10]vrrp vrid 1 priority 120
[sw1]int Vlanif 20
[sw1-Vlanif20]ip add 192.168.2.253 24

//SW2
[sw2]int Vlanif 10
[sw2-Vlanif10]ip add 192.168.1.252 24
[sw2-Vlanif10]vrrp vrid 1 virtual-ip 192.168.1.254
[sw2]int Vlanif 20
[sw2-Vlanif20]ip add 192.168.2.252 24
[sw2-Vlanif20]vrrp vrid 2 virtual-ip 192.168.2.254
[sw2-Vlanif20]vrrp vrid 2 priority 120
