VLAN數(shù)據(jù)流優(yōu)先選擇不同交換機(jī)傳輸，實(shí)現(xiàn)負(fù)責(zé)均衡。將SW1配置為VLAN10，VLAN20和VLAN30的根網(wǎng)橋，SW2配置成VLAN40，VLAN50，VLAN60,VLAN70的根網(wǎng)橋。SW1(config)spanningtree vlan 10 root

secondary2．核心交換機(jī)的路由配置核心交換機(jī)也具備單臂路由功能，實(shí)現(xiàn)是在核心交換機(jī)上為各個(gè)VLAN設(shè)置IP地址作為不同VLAN的網(wǎng)關(guān)，為了使得網(wǎng)絡(luò)更加的穩(wěn)定，使用的HSRP熱備份路由，實(shí)現(xiàn)路由網(wǎng)關(guān)的冗余備份。所以可以結(jié)合單臂路由和HSRP來(lái)使得網(wǎng)絡(luò)更加的穩(wěn)定。由于考慮到本網(wǎng)絡(luò)并不是大型的企業(yè)網(wǎng)絡(luò)，所以我們選用比較簡(jiǎn)單的RIP來(lái)做動(dòng)態(tài)路由。（1）單臂路由結(jié)合HSRPSW1(config)ip
