实验8：VRRP实验

实验拓扑​

1746706768587

MSTP区域配置​

vlan batch 10 20
stp mode mstp
stp region-configuration
region-name mlishu
instance 1 vlan 10
instance 2 vlan 20
active region-configuration

根桥配置​

LSW1作为VLAN 10的根桥，LSW2作为VLAN 20的根桥

LSW1​

stp instance 1 root primary
stp instance 2 root secondary

LSW2​

stp instance 1 root secondary
stp instance 2 root primary

接口配置​

LSW1​

int g0/0/2
port link-type trunk
port trunk allow-pass vlan all
int g0/0/3
port link-type trunk
port trunk allow-pass vlan all
int g0/0/4
port link-type trunk
port trunk allow-pass vlan all

LSW2​

int g0/0/2
port link-type trunk
port trunk allow-pass vlan all
int g0/0/3
port link-type trunk
port trunk allow-pass vlan all
int g0/0/4
port link-type trunk
port trunk allow-pass vlan all

LSW3​

int e0/0/1
port link-type trunk
port trunk allow-pass vlan all
int e0/0/2
port link-type trunk
port trunk allow-pass vlan all
int e0/0/3
port link-type access
port default vlan 10
int e0/0/4
port link-type access
port default vlan 20

LSW4​

int e0/0/1
port link-type trunk
port trunk allow-pass vlan all
int e0/0/2
port link-type trunk
port trunk allow-pass vlan all
int e0/0/3
port link-type access
port default vlan 10
int e0/0/4
port link-type access
port default vlan 20

到这里位置做到了同VLAN间访问，加上下面可以做到跨VLAN访问

VLAN间互访​

LSW1​

int vlanif 10
ip add 192.168.1.254 24
int vlanif 20
ip add 192.168.2.253 24

LSW2​

int vlanif 10
ip add 192.168.1.253 24
int vlanif 20
ip add 192.168.2.254 24

VRRP​

将LSW1作主设备，LSW2作备份设备

LSW1​

# VLANIF10
interface Vlanif10
vrrp vrid 10 virtual-ip 192.168.1.250
vrrp vrid 10 priority 120
vrrp vrid 10 preempt-mode timer delay 20

# VLANIF20
interface Vlanif20
vrrp vrid 20 virtual-ip 192.168.2.250
vrrp vrid 20 priority 120
vrrp vrid 20 preempt-mode timer delay 20

LSW2​

# VLANIF10
interface Vlanif10
vrrp vrid 10 virtual-ip 192.168.1.250
vrrp vrid 10 priority 100
vrrp vrid 10 preempt-mode timer delay 20

# VLANIF20
interface Vlanif20
vrrp vrid 20 virtual-ip 192.168.2.250
vrrp vrid 20 priority 100
vrrp vrid 20 preempt-mode timer delay 20

然后将PC的网关修改为192.168.1.250和192.168.2.250

OSPF​
