实验步骤
1、配置ip地址
r4：
<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysname r4
[r4]int g0/0
[r4-GigabitEthernet0/0]ip add 172.16.1.1 30
[r4-GigabitEthernet0/0]qu
[r4]int LoopBack 0
[r4-LoopBack0]ip add 100.1.1.1 32
[r4-LoopBack0]qu
sw3：
<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysname sw3
--创建vlan
[sw3]vlan 10
[sw3-vlan10]qu
[sw3]vlan 20
[sw3-vlan20]qu
[sw3]vlan 100
[sw3-vlan100]qu
--进入vlan 配置ip地址
[sw3]int vlan 10
[sw3-Vlan-interface10]ip add 192.168.1.254 24
[sw3-Vlan-interface10]qu
[sw3]int vlan 20
[sw3-Vlan-interface20]ip add 192.168.2.254 24
[sw3-Vlan-interface20]quit
[sw3]int vlan 100
[sw3-Vlan-interface100]ip add 172.16.1.2 30
[sw3-Vlan-interface100]quit
2.在SW1和SW2之间配置链路聚合增加链路带宽，提高可靠性
sw1：
<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysname sw1
[sw1]int Bridge-Aggregation 1
[sw1-Bridge-Aggregation1]quit
[sw1]int g1/0/3
[sw1-GigabitEthernet1/0/3]port link-aggregation group 1
[sw1-GigabitEthernet1/0/3]qu
[sw1]int g1/0/4
[sw1-GigabitEthernet1/0/4]port link-aggregation group 1
sw2：
<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysname sw2
[sw2]int Bridge-Aggregation 1
[sw2-Bridge-Aggregation1]qu
[sw2]int g1/0/3
[sw2-GigabitEthernet1/0/3]port link-aggregation group 1
[sw2-GigabitEthernet1/0/3]qu
[sw2]int g1/0/4
[sw2-GigabitEthernet1/0/4]port link-aggregation group 1
3.PC5和PC6属于VLAN10， PC7和PC8属于VLAN20
[sw1]vlan 10
[sw1-vlan10]port g1/0/1
[sw1-vlan10]port g1/0/2
[sw1-vlan10]qu
[sw2]vlan 20
[sw2-vlan20]port g1/0/1
[sw2-vlan20]port g1/0/2
[sw2-vlan20]qu
4.SW1和SW2属于二层交换机，SW3为三层交换机（VLAN100用于对接R4）,在交换机之间相连的链路 放行相关VLAN（不允许放行所有VLAN）
注释：
1、以上我们配置完链路聚合，我们应该在链路聚合里面将链路改为trunk，并且放行vlan10、20
2、因为sw1的g1/0/5这个端口他是处于连接sw3的，这个端口需要配置vlan10、20通行，所有也要为trunk链路
3、因为sw2的g1/0/5这个端口他是处于连接sw3的，这个端口需要配置vlan10、20通行，所有也要为trunk链路
4、在sw3与sw1和sw2相连的接口同样配置trunk，并允许vlan10、20通行
5、将sw3与r4相连的链路加入vlan100
1、将链路聚合配置为trunk，并放行vlan10、20
[sw1]int Bridge-Aggregation 1
[sw1-Bridge-Aggregation1]port link-type trunk
Configuring GigabitEthernet1/0/3 done.
Configuring GigabitEthernet1/0/4 done.
[sw1-Bridge-Aggregation1]port trunk permit vlan 10 20
Configuring GigabitEthernet1/0/3 done.
Configuring GigabitEthernet1/0/4 done.
[sw2]int Bridge-Aggregation 1
[sw2-Bridge-Aggregation1]port link-type trunk
Configuring GigabitEthernet1/0/3 done.
Configuring GigabitEthernet1/0/4 done.
[sw2-Bridge-Aggregation1]port trunk permit vlan 10 20
Configuring GigabitEthernet1/0/3 done.
Configuring GigabitEthernet1/0/4 done.
2、配置sw1的g1/0/5为trunk链路，并放行vlan10 20
[sw1]int g1/0/5
[sw1-GigabitEthernet1/0/5]port link-type trunk
[sw1-GigabitEthernet1/0/5]port trunk permit vlan 10 20
[sw1-GigabitEthernet1/0/5]dis th
#
interface GigabitEthernet1/0/5
port link-mode bridge
port link-type trunk
port trunk permit vlan 1 10 20
combo enable fiber
#
return
3、配置sw2的g1/0/5为trunk链路，并放行vlan10 20
[sw2]int g1/0/5
[sw2-GigabitEthernet1/0/5]port link-type trunk
[sw2-GigabitEthernet1/0/5]port trunk permit vlan 10 20
[sw2]int g1/0/5
[sw2-GigabitEthernet1/0/5]dis th
#
interface GigabitEthernet1/0/5
port link-mode bridge
port link-type trunk
port trunk permit vlan 1 10 20
combo enable fiber
#
return
4、在sw3与sw1和sw2相连的接口同样配置trunk，并允许vlan10、20通行
[sw3]int g1/0/1
[sw3-GigabitEthernet1/0/1]port link-type trunk
[sw3-GigabitEthernet1/0/1]port trunk permit vlan 10 20
[sw3-GigabitEthernet1/0/1]qu
[sw3]int g1/0/2
[sw3-GigabitEthernet1/0/2]port link-type trunk
[sw3-GigabitEthernet1/0/2]port trunk permit vlan 10 20
5、将sw3与r4相连的端口加入vlan100
[sw3]vlan 100
[sw3-vlan100]port g1/0/3
[sw3-vlan100]qu
5.SW3作为DHCP服务器，配置两个地址池，分别为192.168.1.0/24网段和192.168.2.0/24网段网关分 别为192.168.1.254和192.168.2.254，dns统一为114.114.114.114；分别排除地址段192.168.1.1- 192.168.10和192.168.2.1-192.168.2.10
