华为--vrrp配置
1.规划网段
如上图所示：
2.在各交换机上完成基本配置,使得各网段能够互通
sw3配置：
sys
vlan 10
vlan 20
quit
int g0/0/3
port link-type access
port default vlan 10
quit
int g0/0/4
port link-type access
port default vlan 20
quit
int g0/0/1
port link-type trunk
port trunk allow-pass vlan all
quit
int g0/0/2
port link-type trunk
port trunk allow-pass vlan all
quit
在sw5上配置：
sys
vlan 10
vlan 20
vlan 30
int vlan 10
ip add 192.168.10.1 255.255.255.0
int vlan 20
ip add 192.168.20.1 255.255.255.0
int vlan 30
ip add 192.168.30.1 255.255.255.0
int g0/0/1
port link-type trunk
port trunk allow-pass vlan all
int g0/0/2
port link-type access
port default vlan 30
quit
rip 1
network 192.168.10.0
network 192.168.20.0
network 192.168.30.0
在sw5上配置：
sys
vlan 10
vlan 20
vlan 40
int vlan 10
ip add 192.168.10.2 255.255.255.0
int vlan 20
ip add 192.168.20.2 255.255.255.0
int vlan 40
ip add 192.168.40.1 255.255.255.0
int g0/0/1
port link-type trunk
port trunk allow-pass vlan all
int g0/0/2
port link-type access
port default vlan 40
quit
rip 1
network 192.168.10.0
network 192.168.20.0
network 192.168.40.0
在R1上配置：
sys
int g0/0/1
ip add 192.168.30.1 255.255.255.0
quit
int e0/0/0
ip add 192.168.40.1 255.255.255.0
int g0/0/0
ip add 192.168.50.1 255.255.255.0
quit
rip 1
net 192.168.30.0
net 192.168.40.0
net 192.168.50.0
3.在LSW5和LSW6上配置vrrp
注意：对于VLAN10主设备为sw5备设备为sw6，对于VLAN20，主设备为sw6备设备为sw5
sw5配置：
in vlanif 10
vrrp vrid 1 virtual-ip 192.168.10.254
vrrp vrid 1 priority 200
vrrp vrid 1 preempt-mode timer delay 0
vrrp vrid 1 track interface g0/0/2 reduced 200
quit
in vlanif 20
vrrp vrid 2 virtual-ip 192.168.20.254
quit
sw6配置：
in vlanif 10
vrrp vrid 1 virtual-ip 192.168.10.254
quit
in vlanif 20
vrrp vrid 2 virtual-ip 192.168.20.254
vrrp vrid 2 priority 200
vrrp vrid 2 preempt-mode timer delay 0
vrrp vrid 2 track interface g0/0/2 reduced 200 quit
6测试：
当配置完成后：用pc1
tracert 192.168.50.2
当配置完成后：用pc2
tracert 192.168.50.2
断开sw5时，pc1测试
tracert 192.168.50.2
断开sw6时，pc2测试
tracert 192.168.50.2
测试断开上行口：
断开sw5的上行口
pc1测试tracert 192.168.50.2
说明检测到上行口断开后备份交换机自动开启路由转发功能
断开sw6的上行口
pc2测试tracert 192.168.50.2
说明检测到上行口断开后备份交换机自动开启路由转发功能
