实验拓扑

实验需求

（1）SW3和SW2的链路在VLAN10中阻塞，VLAN20中转发 （2）SW3和SW1的链路在VLAN20中阻塞，VLAN10中转发

配置代码

IP配置

AR

int g0/0/0
	ip add 100.1.1.1 30
int g0/0/1
	ip add 100.1.1.5 30
int lo0
	ip add 1.1.1.1 32
	quit
ospf
	area 0
		network 100.1.1.0 0.0.0.3
		network 100.1.1.4 0.0.0.3
		network 1.1.1.1 0.0.0.0
		quit
	quit

LSW1

vlan batch 10 20 100
int vlanif 10
	ip add 192.168.10.254 24
int vlanif 100
	ip add 100.1.1.2 30
	quit
ospf
	area 0
		network 100.1.1.0 0.0.0.3
		network 192.168.10.0 0.0.0.255
		quit
	quit
int g0/0/3
	port link-type access
	port default vlan 100
	quit

LSW2

vlan batch 10 20 100
int vlanif 20
	ip add 192.168.20.254 24
int vlanif 100
	ip add 100.1.1.6 30
	quit
ospf
	area 0
		network 100.1.1.4 0.0.0.3
		network 192.168.20.0 0.0.0.255
		quit
	quit
int g0/0/3
	port link-type access
	port default vlan 100
	quit

修改接口模式

LSW1

int g0/0/1
	port link-type trunk
	port trunk allow-pass vlan 10 20
int g0/0/2
	port link-type trunk
	port trunk allow-pass vlan 10 20
	quit

LSW2

int g0/0/1
	port link-type trunk
	port trunk allow-pass vlan 10 20
int g0/0/2
	port link-type trunk
	port trunk allow-pass vlan 10 20
	quit

LSW3

vlan batch 10 20
int e0/0/5
	port link-type trunk
	port trunk allow-pass vlan 10 20
int e0/0/6
	port link-type trunk
	port trunk allow-pass vlan 10 20
int e0/0/1
	port link-type access
	port default vlan 10
int e0/0/2
	port link-type access
	port default vlan 20
int e0/0/3
	port link-type access
	port default vlan 10
int e0/0/4
	port link-type access
	port default vlan 20

MSTP域配置

stp region-configuration
region-name gyy
	instance 1 vlan 10
	instance 2 vlan 20
	revision-level 1
	active region-configuration
	quit
stp enable
stp mode mstp

配置VLAN10根桥

stp instance 1 root primary
stp instance 1 root secondary

配置VLAN20根桥

stp instance 2 root primary
stp instance 2 root secondary

测试

查看根桥 访问1.1.1.1
