華為網(wǎng)絡(luò)-三層交換配置

• 使用三層交換技術(shù)實(shí)現(xiàn)vlan間通信
  

• 三次交換=二層交換+三層轉(zhuǎn)發(fā)

• 三層轉(zhuǎn)發(fā)過程中要重新封裝2層

• 三層交換機(jī)上，第三層引擎處理數(shù)據(jù)流的第一個包
  

• 一次路由，多次交換

實(shí)驗(yàn)拓?fù)鋱D

實(shí)驗(yàn)步驟：

1、配置sw2交換機(jī)

<Huawei>sys
[Huawei]sysname?SW2
[SW2]vlan?batch?10?20??##創(chuàng)建vlan10?20
[SW2]int?e0/0/2[SW2-Ethernet0/0/2]port?link-type?access???##設(shè)置access
[SW2-Ethernet0/0/2]port?default?vlan?10????##將接口放到vlan中
[SW2-Ethernet0/0/2]un?sh
[SW2-Ethernet0/0/2]int?e0/0/3
[SW2-Ethernet0/0/3]port?link-type?access
[SW2-Ethernet0/0/3]port?default?vlan?20
[SW2-Ethernet0/0/3]un?sh
[SW2-Ethernet0/0/3]int?e0/0/1
[SW2-Ethernet0/0/1]port?link-type?trunk??????##設(shè)置trunk
[SW2-Ethernet0/0/1]port?trunk?allow-pass?vlan?all???##允許所有的vlan通過
[SW2-Ethernet0/0/1]un?sh
[SW2-Ethernet0/0/1]int?g0/0/1
[SW2-GigabitEthernet0/0/1]port?link-type?trunk??
[SW2-GigabitEthernet0/0/1]port?trunk?allow-pass?vlan?all?
[SW2-GigabitEthernet0/0/1]un?sh

2、配置sw3交換機(jī)（與sw2的配置一樣）

<Huawei>sys???
[Huawei]sysname?SW3???
[SW3]vlan?batch?10?20??
[SW3]int?e0/0/2?
[SW3-Ethernet0/0/2]port?link-type?access?
[SW3-Ethernet0/0/2]port?default?vlan?10
[SW3-Ethernet0/0/2]un?sh
[SW3-Ethernet0/0/2]int?e0/0/3
[SW3-Ethernet0/0/3]port?link-type?access????
[SW3-Ethernet0/0/3]port?default?vlan?20
[SW3-Ethernet0/0/3]un?sh
[SW3-Ethernet0/0/3]int?e0/0/1
[SW3-Ethernet0/0/1]port?link-type?trunk?
[SW3-Ethernet0/0/1]port?trunk?allow-pass?vlan?all?
[SW3-Ethernet0/0/1]un?sh

3、配置sw1三層交換機(jī)

<Huawei>sys
[Huawei]sysname?SW1
[SW1]vlan?batch?10?20?1000
[SW1]int?g0/0/1
[SW1-GigabitEthernet0/0/1]port?link-type?trunk?
[SW1-GigabitEthernet0/0/1]port?trunk?allow-pass?vlan?all?
[SW1-GigabitEthernet0/0/1]un?sh
[SW1-GigabitEthernet0/0/1]int?g0/0/2???
[SW1-GigabitEthernet0/0/2]port?link-type?access???
##三層交換連接路由的不能配置trunk
[SW1-GigabitEthernet0/0/2]port?default?vlan?1000
[SW1-GigabitEthernet0/0/2]un?sh
[SW1-GigabitEthernet0/0/2]q
[SW1]int?vlanif?10???##進(jìn)入邏輯接口[SW1-Vlanif10]ip?add?192.168.10.1?24??##設(shè)置網(wǎng)關(guān)
[SW1-Vlanif10]int?vlanif?20[SW1-Vlanif20]ip?add?192.168.20.1?24
[SW1]int?vlanif?1000
[SW1-Vlanif1000]ip?add?11.0.0.1?30
[SW1-Vlanif1000]q
[SW1]ip?route-static?0.0.0.0?0.0.0.0?11.0.0.2??##設(shè)置默認(rèn)路由，向上默認(rèn)，向下靜態(tài)

4、配置R1路由

<Huawei>sys
[Huawei]sysname?R1
[R1]int?g0/0/0???##設(shè)置接口的ip地址
[R1-GigabitEthernet0/0/0]ip?add?11.0.0.2?30
[R1-GigabitEthernet0/0/0]un?sh
[R1-GigabitEthernet0/0/0]int?loopback?0??##進(jìn)入回環(huán)接口，設(shè)置ip
[R1-LoopBack0]ip?add?1.1.1.1?30
[R1-LoopBack0]q
[R1]ip?route-static?192.168.10.0?24?11.0.0.1?##設(shè)置靜態(tài)路由
[R1]ip?route-static?192.168.20.0?24?11.0.0.1

5、測試全網(wǎng)互通性

實(shí)驗(yàn)完成。
