1. 使能LSW3、LSW4、LSW5、LSW6的生成树计算功能
[LSW3]stp enable
[LSW4]stp enable
[LSW5]stp enable
[LSW6]stp enable
2. 配置LSW3、LSW4发送到LSW1的STP协议报文带Tag100，配置LSW5、LSW6发送到LSW2的STP协议报文带Tag200
[LSW3]vlan 100
[LSW3-GigabitEthernet0/0/1]port link-type hybrid
[LSW3-GigabitEthernet0/0/1]port hybrid tagged vlan 100
[LSW3-GigabitEthernet0/0/1]stp bpdu vlan 100
[LSW4]vlan 200
[LSW4-GigabitEthernet0/0/1]port link-type hybrid
[LSW4-GigabitEthernet0/0/1]port hybrid tagged vlan 200
[LSW4-GigabitEthernet0/0/1]stp bpdu vlan 200
[LSW5]vlan 100
[LSW5-GigabitEthernet0/0/1]port link-type hybrid
[LSW5-GigabitEthernet0/0/1]port hybrid tagged vlan 100
[LSW5-GigabitEthernet0/0/1]stp bpdu vlan 100
[LSW6]vlan 200
[LSW6-GigabitEthernet0/0/1]port link-type hybrid
[LSW6-GigabitEthernet0/0/1]port hybrid tagged vlan 200
[LSW6-GigabitEthernet0/0/1]stp bpdu vlan 200
3. 配置LSW1、LSW2的接口，使收到的STP协议报文可以透明传输到对端
[LSW1]vlan batch 100 200
[LSW1-GigabitEthernet0/0/2]port link-type hybrid
[LSW1-GigabitEthernet0/0/2]port hybrid tagged vlan 100
[LSW1-GigabitEthernet0/0/2]l2protocol-tunnel stp vlan 100
[LSW1-GigabitEthernet0/0/3]port link-type hybrid
[LSW1-GigabitEthernet0/0/3]port hybrid tagged vlan 200
[LSW1-GigabitEthernet0/0/3]l2protocol-tunnel stp vlan 200
[LSW1-GigabitEthernet0/0/1]port link-type trunk
[LSW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 100 200
[LSW2]vlan batch 100 200
[LSW2-GigabitEthernet0/0/2]port link-type hybrid
[LSW2-GigabitEthernet0/0/2]port hybrid tagged vlan 100
[LSW2-GigabitEthernet0/0/2]l2protocol-tunnel stp vlan 100
[LSW2-GigabitEthernet0/0/3]port link-type hybrid
[LSW2-GigabitEthernet0/0/3]l2protocol-tunnel stp vlan 200
[LSW2-GigabitEthernet0/0/3]port link-type hybrid
[LSW2-GigabitEthernet0/0/1]port link-type trunk
[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 100 200
4. 配置LSW1、LSW2替换接收到的STP协议报文的MAC地址
[LSW1]l2protocol-tunnel stp group-mac 0100-0100-0100
[LSW2]l2protocol-tunnel stp group-mac 0100-0100-0100
5. 配置LSW5、LSW6的优先级为4096
[LSW5]stp priority 4096
[LSW6]stp priority 4096
6. 检查配置
