VRRP的基本配置（以H3C模拟器为例）

VRRP的基本配置：

 

S1:

sys

[H3C]sys S1

[S1]vlan 10

[S1-vlan10]port g1/0/1

[S1-vlan10]vlan 20

[S1-vlan20]port g1/0/2

[S1-vlan20]vlan 30

[S1-vlan30]port g1/0/3

[S1-vlan30]vlan 40

[S1-vlan40]port g1/0/4

[S1-vlan40]int range g1/0/5 to g1/0/6

[S1-if-range]port link-type trunk

[S1-if-range]port trunk permit vlan all

[S1-if-range]qu

S2:

[S2]vlan 10

[S2-vlan10]vlan 20

[S2-vlan20]vlan 30

[S2-vlan30]vlan 40

[S2-vlan40]int vlan 10

[S2-Vlan-interface10]ip ad 192.168.10.1 24

[S2-Vlan-interface10]vrrp vrid 10 virtual-ip 192.169.10.254

[S2-Vlan-interface10]vrrp vrid 10 priority 110

[S2-Vlan-interface10]vrrp vrid 10 preempt-mode delay 5

[S2-Vlan-interface10]int vlan 20

[S2-Vlan-interface20]ip ad 192.168.20.1 24

This subnet overlaps with another interface!

[S2-Vlan-interface20]vrrp vrid 10 virtual-ip 192.169.20.254

[S2-Vlan-interface20]vrrp vrid 10 priority 110

[S2-Vlan-interface20]vrrp vrid 10 preempt-mode delay 5

[S2-Vlan-interface20]int vlan 30

[S2-Vlan-interface30]ip ad 192.168.30.1 24

[S2-Vlan-interface30]vrrp vrid 10 virtual-ip 192.169.30.254

[S2-Vlan-interface30]vrrp vrid 10 priority 100

[S2-Vlan-interface30]vrrp vrid 10 preempt-mode delay 5

[S2-Vlan-interface30]int vlan 40

[S2-Vlan-interface40]ip ad 192.168.40.1 24

[S2-Vlan-interface40]vrrp vrid 10 virtual-ip 192.169.40.254

[S2-Vlan-interface40]vrrp vrid 10 priority 100

[S2-Vlan-interface40]vrrp vrid 10 preempt-mode delay 5

[S2-Vlan-interface40]qu

验证vrrp冗余网关是否配置成功：

[S2]dis vrrp
