好的,根据您更新后的网络拓扑,以下是使用STP协议配置思科交换机的命令:
1. 配置左侧三层交换机:
```
spanning-tree mode rapid-pvst
spanning-tree vlan 10,20,30 root primary
```
2. 配置左侧二层交换机1:
```
spanning-tree mode rapid-pvst
spanning-tree vlan 10,20,30 root secondary
interface FastEthernet 0/1
switchport mode access
switchport access vlan 10
spanning-tree portfast
```
3. 配置左侧二层交换机2:
```
spanning-tree mode rapid-pvst
spanning-tree vlan 10,20,30 root secondary
interface FastEthernet 0/1
switchport mode access
switchport access vlan 20
spanning-tree portfast
```
4. 配置中间路由器:
```
spanning-tree mode rapid-pvst
spanning-tree vlan 10,20,30 root primary
```
5. 配置右侧路由器:
```
spanning-tree mode rapid-pvst
spanning-tree vlan 10,20,30 root secondary
```
6. 配置右侧三层交换机1:
```
spanning-tree mode rapid-pvst
spanning-tree vlan 10,20,30 root primary
interface FastEthernet 0/1
switchport mode access
switchport access vlan 20
spanning-tree portfast
```
7. 配置右侧三层交换机2:
```
spanning-tree mode rapid-pvst
spanning-tree vlan 10,20,30 root primary
interface FastEthernet 0/1
switchport mode access
switchport access vlan 30
spanning-tree portfast
```
注意:以上命令仅供参考,具体的STP配置需要根据实际需求进行调整。
