单臂路由+DHCP
实验拓扑图：
R1
f0/1
e0/0
实验要求：
PC1和PC2要分配到地址，而且能相互通。
实验步骤：
1. 配置PC 机
PC1(config)#no ip routing
PC1(config)#int e0/0
PC1(config-if)#du fu
PC1(config-if)#no sh
PC2(config)#no ip routing
PC2(config)#int e0/0
PC2(config-if)#no sh
PC2(config-if)#du fu
2. 配置路由器：
sW#vlan database
sW(vlan)#vlan 2
VLAN 2 added:
Name: VLAN0002
sW(vlan)#vlan 3
VLAN 3 added:
Name: VLAN0003
sW(vlan)#exit
sW(config)#int fa0/2
sW(config-if)#sw
sW(config-if)#switchport acc vlan 2 （把端口加进vlan2里）
sW(config-if)#int fa0/3
sW(config-if)#sw
sW(config-if)#switchport access vlan 3
sW(config-if)#^Z
sW#sh vlan-sw
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Fa0/0, Fa0/1, Fa0/4, Fa0/5
Fa0/6, Fa0/7, Fa0/8, Fa0/9
Fa0/10, Fa0/11, Fa0/12, Fa0/13
Fa0/14, Fa0/15
2 VLAN0002 active Fa0/2
3 VLAN0003 active Fa0/3
1002 fddi-default active 0020
sW(config)#int fa0/1
sW(config-if)#sw
sW(config-if)#switchport mo
sW(config-if)#switchport mode t
sW(config-if)#switchport mode trunk （将端口配置成trunk（端口汇聚）模式）
3.配置路由器：
R1(config-if)#int e0/0.1
R1(config-subif)#en
R1(config-subif)#encapsulation do
R1(config-subif)#encapsulation dot1Q 2 （封装802.1q）
R1(config-subif)#ip add 10.0.0.254 255.255.255.0
R1(config-subif)#no sh
R1(config-subif)#
R1(config-subif)#
R1(config-subif)#
R1(config-subif)#int e0/0.2
R1(config-subif)#en do 3
R1(config-subif)#ip add 20.0.0.254 255.255.255.0
R1(config-subif)#no sh
R1(config-subif)#
R1(config-subif)#
R1(config-subif)#exit
R1(config)#ip dhcp pool
R1(config)#ip dhcp pool vlan2
R1(dhcp-config)#defa
R1(dhcp-config)#default-router 10.0.0.254 255.255.255.0 （配置网关地址）
R1(dhcp-config)#netwo
R1(dhcp-config)#network 10.0.0.0 255.255.255.0 （指定地址池）
R1(dhcp-config)#lease 7 （租约时间）
R1(dhcp-config)#ip dhcp excluded-add
R1(dhcp-config)#i p dhcp excluded-add 10.0.0.1 10.0.0.10 （设置保留地址）
R1(config)#
R1(config)#ip dhcp pool valn3
R1(dhcp-config)#defa 20.0.0.254 255.255.255.0
R1(dhcp-config)#net 20.0.0.0 255.255.255.0
% Ambiguous command: "net 20.0.0.0 255.255.255.0"
R1(dhcp-config)#netwo 20.0.0.0 255.255.255.0
R1(dhcp-config)#lease 6
R1(dhcp-config)#ip dhcp excluded-add 20.0.0.1 20.0.0.6
R1(config)#^Z
结果：
R1#sh ip dhcp binding
Bindings from all pools not associated with VRF:
IP address Client-ID/ Lease expiration Type
Hardware address/
User name
R1#sh ip dhcp binding
Bindings from all pools not associated with VRF:
IP address Client-ID/ Lease expiration Type
Hardware address/
User name

PC1#ping 20.0.0.7
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 20.0.0.7, timeout is 2 seconds:
.!!!! （可以通信）
Success rate is 80 percent (4/5), round-trip min/avg/max = 28/55/104 ms
PC1#
PC2#sh ip int b
Interface IP-Address OK? Method Status Protocol
Ethernet0/0 20.0.0.7 YES DHCP up up （获得指定内的IP）
总结：实验成功，对几个命令不是很熟悉，耽误了一点时间。
