实验拓扑
实验要求： 利用MSTP实现vlan10和vlan20互访 实验步骤： 1.配置客户端和路由ip R1: [r1]int g0/0/0 [r1-GigabitEthernet0/0/0]ip add 192.168.10.254 24 [r1-GigabitEthernet0/0/0]undo sh [r1-GigabitEthernet0/0/0]int g0/0/1 [r1-GigabitEthernet0/0/1]ip add 192.168.20.254 24 [r1-GigabitEthernet0/0/1]undo sh
客户端：
2.配置vlan及trunk SW1： [sw1]vlan batch 10 20 [sw1]int e 0/0/2 [sw1-Ethernet0/0/2]port link-type trunk [sw1-Ethernet0/0/2]port trunk allow-pass vlan all [sw1-Ethernet0/0/2]int e 0/0/3 [sw1-Ethernet0/0/3]port link-type trunk [sw1-Ethernet0/0/3]port trunk allow-pass vlan all [sw1-Ethernet0/0/3]int e 0/0/1 [sw1-Ethernet0/0/1]port link-type hybrid [sw1-Ethernet0/0/1]port hybrid untagged vlan 10 [sw1-Ethernet0/0/1]port hybrid pvid vlan 10
SW2: [sw2]vlan batch 10 20 [sw2]int e 0/0/2 [sw2-Ethernet0/0/2]port link-type trunk [sw2-Ethernet0/0/2]port trunk allow-pass vlan all [sw2-Ethernet0/0/2]int e 0/0/3 [sw2-Ethernet0/0/3]port link-type trunk [sw2-Ethernet0/0/3]port trunk allow-pass vlan all [sw2-Ethernet0/0/3]q [sw2]int e 0/0/1 [sw2-Ethernet0/0/1]port link-type hybrid [sw2-Ethernet0/0/1]port hybrid untagged vlan 20 [sw2-Ethernet0/0/1]port hybrid pvid vlan 20
SW3：[sw3]vlan batch 10 20[sw3]int e 0/0/2[sw3-Ethernet0/0/2]port link-type access[sw3-Ethernet0/0/2]port default vlan 10[sw3-Ethernet0/0/2]int e 0/0/3[sw3-Ethernet0/0/3]port link-type access[sw3-Ethernet0/0/3]port default vlan 20[sw3-Ethernet0/0/3]q[sw3]int e 0/0/1[sw3-Ethernet0/0/1]port link-type trunk[sw3-Ethernet0/0/1]port trunk allow-pass vlan all[sw3-Ethernet0/0/1]int e 0/0/4[sw3-Ethernet0/0/4]port link-type trunk[sw3-Ethernet0/0/4]port trunk allow-pass vlan all
3.配置MSTP： SW1： [sw1]stp mode mstp[sw1]stp region-configuration [sw1-mst-region]region-name benet.com [sw1-mst-region]revision-level 1 [sw1-mst-region]instance 1 vlan 10 [sw1-mst-region]instance 2 vlan 20 [sw1-mst-region]active region-configurationInfo [sw1-mst-region]q [sw1]stp instance 1 root primary [sw1]stp instance 2 root
SW2: [sw2]stp mode mstp [sw2]stp region-configuration [sw2-mst-region]region-name benet.com [sw2-mst-region]revision-level 1 [sw2-mst-region]instance 1 vlan 10 [sw2-mst-region]instance 2 vlan 20 [sw2-mst-region]active region-configuration [sw2-mst-region]q [sw2]stp instance 2 root primary [sw2]stp instance 1 root secondary
SW3:
[sw3]stp mode mstp [sw3]stp region-configuration [sw3-mst-region]region-name benet.com [sw3-mst-region]revision-level 1 [sw3-mst-region]instance 1 vlan 10 [sw3-mst-region]instance 2 vlan 20 [sw3-mst-region]active region-configuration
