VRRP+MSTP实验

搭建简易的VRRP+MSTP实验

虚拟VIP配合多生成树协议

实验拓扑

LSW3上的配置

先创建vlan10、20
vlan batch 10 20

然后在接口下划分trunk、access模式
interface GE0/0/1
 port link-type access
 port default vlan 10
interface GE0/0/2
 port link-type access
 port default vlan 20
interface GE/0/3
 port link-type trunk
 port trunk allow-pass vlan 10 20
interface GE0/0/4
 port link-type trunk
 port trunk allow-pass vlan 10 20
 
 配置mstp
 stp mode mstp
 stp region-configuration
 region-name liu
 instance 10 vlan 10
 instance 20 vlan 20
 active region-configuration
 
 验证

 LSW1上的配置

先创建vlan10、20
vlan batch 10 20

配置链路聚合和trunk口
interface Eth-Trunk1
trunkport int g0/0/1
trunkport int g0/0/2
interface Eth-Trunk1
port link-type trunk
port trunk allow-pass vlan 10 20
interface GigabitEthernet0/0/3
port link-type trunk
port trunk allow-pass vlan 10 20

配置mstp
stp mode mstp
stp region-configuration
region-name liu
instance 10 vlan 10
instance 20 vlan 20
active region-configuration
stp instance 10 root primary
stp instance 20 root secondary

配置VRRP
interface Vlanif10
ip address 192.168.10.253 255.255.255.0
vrrp vrid 10 virtual-ip 192.168.10.254
vrrp vrid 10 priority 120
interface Vlanif20
ip address 192.168.20.252 255.255.255.0
vrrp vrid 20 virtual-ip 192.168.20.254
 vrrp vrid 20 priority 100

配置完SW2 VLAN20就会变成BackUP
