利用華為模擬器eNSP來設(shè)計(jì)邏輯網(wǎng)絡(luò)拓樸圖，有一臺路由器AR201，一臺二層交換機(jī)S5700，二臺PC主機(jī)。其之間用線纜連接并作好標(biāo)注。
注意：連接好線纜后設(shè)置PC1和PC2的IP地址、子網(wǎng)掩碼及網(wǎng)關(guān)，其中網(wǎng)關(guān)為路由器中設(shè)置的IP地址。
1 實(shí)現(xiàn)不同vlan間的通信方法之——單臂路由
1.1 配置交換機(jī)
system-view
sysname SW1 //設(shè)置交換機(jī)名字為SW1
vlan batch 2 3 //連續(xù)創(chuàng)建vlan 2 3
interface Ethernet 0/0/2
port link-type access //設(shè)置端口類型為access
port default vlan 2 //將接口劃分到vlan 2
quit
interface Ethernet 0/0/3
port link-type access
port default vlan 3
quit
interface Ethernet 0/0/1
port link-type trunk //設(shè)置端口類型為trunk
port trunk allow-pass vlan 2 3 //華為交換機(jī)默認(rèn)不支持其他vlan通過，除去vlan 1,允許trunk端口通過vlan 2 3
1.2 配置路由器
system-view
sysname R1 //設(shè)置路由器名字R1
display interface brief //顯示接口概要
interface GigabitEthernet 0/0/0.1
dot1q termination vid 2 //封裝dot1q協(xié)議,該子接口對應(yīng)vlan 2
ip address 192.168.2.254 24 //設(shè)置子接口IP地址和子網(wǎng)掩碼
arp broadcast enable //開啟子接口的ARP廣播
quit
interface GigabitEthernet 0/0/0.2
dot1q termination vid 3
ip address 192.168.3.254 24
arp broadcast enable
quit
display ip interface brief //顯示接口IP的簡要狀態(tài)信息
ping 192.168.2.2 //測試能夠ping通
ping 192.168.3.3
