一、組網(wǎng)需求

內(nèi)網(wǎng)有4個(gè)vlan，vlan10和20的生成樹(shù)根橋在核心交換機(jī)A上，vlan30,40的vlan根橋在核心交換機(jī)B上。

二、組網(wǎng)拓?fù)?#xff1a;

三、配置要點(diǎn)：

開(kāi)啟生成樹(shù)功能

創(chuàng)建不同的實(shí)例

為實(shí)例配置優(yōu)先級(jí)

四、配置步驟：

注意：配置之前建議使用 Ruijie#show interface status查看接口名稱，常用接口名稱有FastEthernet(百兆)、GigabitEthernet(千兆)和TenGigabitEthernet(萬(wàn)兆),以下配置以百兆接口為例。

核心交換機(jī)A配置：

Ruijie>enable?????????????????? ------>進(jìn)入特權(quán)模式

Ruijie#configure terminal??????? ------>進(jìn)入全局配置模式

Ruijie(config)#vlan 10??? ------>創(chuàng)建vlan 10 、20、30和40

Ruijie(config-vlan)#vlan 20

Ruijie(config-vlan)#vlan 30

Ruijie(config-vlan)#vlan 40

Ruijie(config-vlan)#exit

Ruijie(config)#spanning-tree? ?------>開(kāi)啟生成樹(shù)，默認(rèn)模式是 mst

Ruijie(config)#spanning-tree mst configuration??? ------>配置mst

Ruijie(config-mst)# instance 1 vlan 10, 20??????????? ------>vlan 10和20 使用實(shí)例(instance)1

Ruijie(config-mst)# instance 2 vlan 30, 40??????????? ------>vlan 30和40使用實(shí)例2

Ruijie(config-mst)#spanning-tree mst 1 priority 4096?? ------>實(shí)例1 的優(yōu)先級(jí)為4096，越小越優(yōu)先，默認(rèn)優(yōu)先級(jí)是32768

Ruijie(config-mst)#exit

Ruijie(config)#interface FastEthernet 0/1

Ruijie(config-if-FastEthernet 0/1)#switch mode trunk------>把交換機(jī)的第一個(gè)百兆接口配置成trunk

Ruijie(config)#interface FastEthernet 0/2

Ruijie(config-if-FastEthernet 0/2)#switch mode trunk------>把交換機(jī)的第二個(gè)百兆接口配置成trunk

核心交換機(jī)B配置：

Ruijie>enable?????????????????? ------>進(jìn)入特權(quán)模式

Ruijie#configure terminal??????? ------>進(jìn)入全局配置模式

Ruijie(config)#vlan 10??? ------>創(chuàng)建vlan 10 、20、30和40

Ruijie(config-vlan)#vlan 20

Ruijie(config-vlan)#vlan 30

Ruijie(config-vlan)#vlan 40

Ruijie(config-vlan)#exit

Ruijie(config)#spanning-tree

Ruijie(config)#spanning-tree mst configuration

Ruijie(config-mst)# instance 1 vlan 10, 20

Ruijie(config-mst)# instance 2 vlan 30, 40

Ruijie(config-mst)#spanning-tree mst 2 priority 4096

Ruijie(configmst)#exit

Ruijie(config)#interface FastEthernet 0/1

Ruijie(config-if-FastEthernet 0/1)#switch mode trunk------>把交換機(jī)的第一個(gè)百兆接口配置成trunk

Ruijie(config)#interface FastEthernet 0/2

Ruijie(config-if-FastEthernet 0/2)#switch mode trunk------>把交換機(jī)的第二個(gè)百兆接口配置成trunk

接入交換機(jī)配置：

Ruijie>enable?????????????????? ------>進(jìn)入特權(quán)模式

Ruijie#configure terminal??????? ------>進(jìn)入全局配置模式

Ruijie(config)#vlan 10??? ------>創(chuàng)建vlan 10 、20、30和40

Ruijie(config-vlan)#vlan 20

Ruijie(config-vlan)#vlan 30

Ruijie(config-vlan)#vlan 40

Ruijie(config-vlan)#exit

Ruijie(config)#spanning-tree

Ruijie(config)#spanning-tree mst configuration

Ruijie(config-mst)# instance 1 vlan 10, 20

Ruijie(config-mst)# instance 2 vlan 30, 40

Ruijie(config-mst)#exit

Ruijie(config)#interface FastEthernet 0/1

Ruijie(config-if-FastEthernet 0/1)#switch mode trunk------>把交換機(jī)的第一個(gè)百兆接口配置成trunk

Ruijie(config)#interface FastEthernet 0/2

Ruijie(config-if-FastEthernet 0/2)#switch mode trunk------>把交換機(jī)的第二個(gè)百兆接口配置成trunk

保存配置

Ruijie(config)#end????????????? ??------>退出到特權(quán)模式

Ruijie#write??????????????? ???------>確認(rèn)配置正確，保存配置

五、配置驗(yàn)證：

Ruijie#show spanning-tree summary

Spanning tree enabled protocol mstp

MST 0 vlans map : 1-9, 11-19, 21-29, 31-39, 41-4094???? ------>哪些vlan使用實(shí)例0，實(shí)例0是默認(rèn)實(shí)例，沒(méi)有配置的vlan都屬于該實(shí)例

Root ID??? Priority??? 32768???????????????????????????? ------>根id優(yōu)先級(jí)
