双核心交换机MSTP+VRRP双活初级配置教程【详解】

一、拓扑图

二、基础配置步骤

1.交换机基础配置

  (1)SW1配置

[SW1] vlan batch 2 10 20      //建立vlan 2、10、20 
[SW1] interface Vlanif 2         //进入vlan 2
[SW1-Vlanif10] ip address 10.1.1.1 24       //配置vlan 2的网关，一般用于交换机管理地址
[SW1] interface GigabitEthernet 0/0/1              //进入1接口
[SW1-GigabitEthernet0/0/1] port link-type trunk       //配置1接口为trunk（新手说明：trunk允许多个vlan通过，access只允许一个vlan通过）
[SW1-GigabitEthernet0/0/1] port trunk allow-pass vlan all   //允许1接口通过的vlan为所有
[SW1]# interface GigabitEthernet 0/0/2
[SW1-GigabitEthernet0/0/2] port link-type trunk
[SW1-GigabitEthernet0/0/2] port trunk allow-pass vlan all

（2）SW2配置

[SW2] vlan batch 2 10 20    //建立vlan 2、10、20
[SW2] interface Vlanif 2       //进入vlan 2
[SW2-Vlanif10] ip address 10.1.1.2 24   //配置vlan 2的网关，一般用于交换机管理地址
[SW2] interface GigabitEthernet 0/0/1       //进入1接口
[SW2-GigabitEthernet0/0/1] port link-type trunk      //配置1接口为trunk
[SW2-GigabitEthernet0/0/1] port trunk allow-pass vlan all      //允许1接口通过的vlan为所有
[SW2]# interface GigabitEthernet 0/0/2
[SW2-GigabitEthernet0/0/2] port link-type trunk
[SW2-GigabitEthernet0/0/2] port trunk allow-pass vlan all

（3）SW3配置

[SW3] vlan batch 2 10             //建立vlan 2、10
[SW3] interface Vlanif 2          //进入vlan 2
[SW3-Vlanif10] ip address 10.1.1.3 24     //配置vlan 2的网关，一般用于交换机管理地址
[SW3] interface Ethernet 0/0/1     //进入1接口
[SW3-Ethernet0/0/1] port link-type trunk             //配置1接口为trunk
[SW3-Ethernet0/0/1] port trunk allow-pass vlan all   //允许1接口通过的vlan为所有
[SW3]# interface Ethernet 0/0/2
[SW3-Ethernet0/0/2] port link-type trunk
[SW3-Ethernet0/0/2] port trunk allow-pass vlan all
[SW3]# interface Ethernet 0/0/20
[SW3-Ethernet0/0/20] port link-type access    //配置20接口为access
[SW3-Ethernet0/0/20] port default vlan 10     //配置20接口只允许通过vlan10

（4）SW4配置

[SW4] vlan batch 2 20             //建立vlan 2、10
[SW4] interface Vlanif 2          //进入vlan 2
[SW4-Vlanif10] ip address 10.1.1.4 24     //配置vlan 2的网关，一般用于交换机管理地址
[SW4] interface Ethernet 0/0/1     //进入1接口
[SW4-Ethernet0/0/1] port link-type trunk             //配置1接口为trunk
[SW4-Ethernet0/0/1] port trunk allow-pass vlan all   //允许1接口通过的vlan为所有
[SW4]# interface Ethernet 0/0/2
[SW4-Ethernet0/0/2] port link-type trunk
[SW4-Ethernet0/0/2] port trunk allow-pass vlan all
[SW4]# interface Ethernet 0/0/20
[SW4-Ethernet0/0/20] port link-type access    //配置20接口为access
[SW4-Ethernet0/0/20] port default vlan 20     //配置20接口只允许通过vlan20
