交换综合实验
需求![]()
教学楼1二层使用MSTP进行防环
vlan2属于实例1，vlan3属于实例2
sw4作为实例1的主根，实例2的备份根
sw5作为实例2的主根，实例1的备份根，SW4和SW5之间需要做链路聚合。
教学楼2和教学楼1需求相同
SW4和SW13之间启动VRRP，形成网关的互为备份
SW4作为实例1的主网关，实例2 的备份网关
SW13作为实例2的主网关，实例1 的备份网关
主设备上增加20S的转发延迟
主设备增加双上行链路监控，两条链路同时断开才切换设备。
教学楼2和教学楼1 相同
实验步骤
1.创建VLAN
为教学楼1所有交换设备创建VLAN2,VLAN3;教学楼2所有交换设备创建VLAN4,VLAN5
[D1]vlan batch 2 3
其余设备同理
2.链路聚合
[D1]interface Eth-Trunk 0
[D1-Eth-Trunk0]trunkport GigabitEthernet 0/0/1 0/0/2
其余设备同理
3.划分VLAN
[D1]port-group group-member g0/0/3 g0/0/4 g0/0/5 Eth-Trunk 0
[D1-port-group]port link-type trunk
[D1-port-group]port trunk allow-pass vlan 2 3
[D1-port-group]undo port trunk allow-pass vlan 1
[A1]int g0/0/2
[A1-GigabitEthernet0/0/2]port link-type access
[A1-GigabitEthernet0/0/2]port default vlan 2
[A1-GigabitEthernet0/0/2]int g0/0/24
[A1-GigabitEthernet0/0/24]port link-type access
[A1-GigabitEthernet0/0/24]port default vlan 3
[A1-GigabitEthernet0/0/24]int g0/0/1
[A1-GigabitEthernet0/0/1]port link-type trunk
[A1-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 3
[A1-GigabitEthernet0/0/1]undo port trunk allow-pass vlan 1
[A1-GigabitEthernet0/0/1]int g0/0/3
[A1-GigabitEthernet0/0/3]port link-type trunk
[A1-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 3
[A1-GigabitEthernet0/0/3]undo port trunk allow-pass vlan 1
其余设备同理
4.MSTP
[D1]stp mode mstp
[D1]stp enable
[D1]stp region-configuration
[D1-mst-region]region-name jxl1
[D1-mst-region]revision-level 1
[D1-mst-region]instance 1 vlan 2
[D1-mst-region]instance 2 vlan 3
[D1-mst-region]active region-configuration
[D1]stp instance 1 root primary
[D1]stp instance 2 root secondary
[D1]stp instance 2 root primary
[D2]stp instance 1 root secondary
其余同理
5.VSI
[D1]interface Vlanif 2
[D1-Vlanif2]ip address 192.168.2.1 24
[D1]interface Vlanif 3
[D1-Vlanif3]ip address 192.168.3.2 24
其余设备同理
6.VRRP
[D1]int Vlanif 2
[D1-Vlanif2]vrrp vrid 2 virtual-ip 192.168.2.254
[D1-Vlanif2]vrrp vrid 2 priority 110
[D1-Vlanif2]int Vlanif 3
[D1-Vlanif3]vrrp vrid 3 virtual-ip 192.168.3.254
[D2]int Vlanif 2
[D2-Vlanif2]vrrp vrid 2 virtual-ip 192.168.2.254
[D2-Vlanif2]int Vlanif 3
[D2-Vlanif3]vrrp vrid 3 virtual-ip 192.168.3.254
[D2-Vlanif2]vrrp vrid 3 priority 110
其余设备同理
