组网要求:
1、Router为DHCP服务器,开启DHCP服务,为PC分配地址。使用的地址池网段为192.168.1.0/24,并且地址池中需排除掉地址192.168.1.254、192.168.1.253,因为这些地址不能分配给PC。同时为客户端分配的网关地址是192.168.1.254,所分配的地址租期为2天。客户端自动获取的DNS服务器地址为8.8.8.8。
2、SW上部署了两个VLAN:分别是vlan10及vlan20;PC属于VLAN10,Router属于VLAN20;
3、要求PC机能够通过DHCP自动获取地址及网关。

二、IP设置:
PC1:自动获取IP地址,网关自动获取
PC2、自动获取IP地址
SW:vlanif10:192.168.1.254/24
Vlanif20:192.168.2.1/24
Router:192.168.2.2/24
三、配置步骤:
Router的配置如下:
[Router] interface GigabitEthernet 0/0/0
[Router-GigabitEthernet0/0/0] ip address 192.168.2.2 24
[Router] dhcp enable #全局使能DHCP服务
[Router] ip pool dhcppool #创建地址池
[Router-ip-pool-dhcppool] network 192.168.1.0 mask 24
[Router-ip-pool-dhcppool] gateway-list 192.168.1.254
[Router-ip-pool-dhcppool] lease day 2
[Router-ip-pool-dhcppool] dns-list 8.8.8.8
[Router-ip-pool-dhcppool] quit
[Router] interface GigabitEthernet 0/0/0
[Router-GigabitEthernet0/0/0] dhcp select global #使能接口的DHCP服务功能,从该接口从全局地址池分配地址
核心交换机的配置如下:
[SW] vlan batch 10 20
[SW] interface GigabitEthernet 0/0/1
[SW-GigabitEthernet0/0/1] port link-type access
[SW-GigabitEthernet0/0/1] port default vlan 10
[SW] interface GigabitEthernet 0/0/24
[SW-GigabitEthernet0/0/24] port link-type access
[SW-GigabitEthernet0/0/24] port default vlan 20
[SW]interface Vlanif 10
[SW-Vlanif10] ip address 192.168.1.254 24
[SW-Vlanif10] interface vlanif 20
[SW-Vlanif20] ip address 192.168.2.1 24
[SW-Vlanif20] quit
[SW] dhcp enable #交换机首先全局开启DHCP服务
[SW] interface Vlanif 10
[SW-Vlanif10] dhcp select relay #vlanif10使能DHCP中继
[SW-Vlanif10] dhcp relay server-ip 192.168.2.2 #配置DHCP服务器的地址
路由器上增加静态路由:
[Router] ip route-static 192.168.1.0 24 192.168.2.1
完成上述配置后,PC即可正常获取地址。
四、Router的主要配置文件:
#
sysname Router
#
dhcp enable
#
ip pool dhcppool
gateway-list 192.168.1.254
network 192.168.1.0 mask 255.255.255.0
excluded-ip-address 192.168.1.253
lease day 2 hour 0 minute 0
dns-list 8.8.8.8
#
interface GigabitEthernet0/0/0
ip address 192.168.2.2 255.255.255.0
dhcp select global
#
ip route-static 192.168.1.0 255.255.255.0 192.168.2.1
#
return
五、SW的主要配置文件:
#
sysname SW
#
vlan batch 10 20
#
dhcp enable
#
interface Vlanif1
#
interface Vlanif10
ip address 192.168.1.254 255.255.255.0
dhcp select relay
dhcp relay server-ip 192.168.2.2
#
interface Vlanif20
ip address 192.168.2.1 255.255.255.0
#
interface MEth0/0/1
#
interface GigabitEthernet0/0/1
port link-type access
port default vlan 10
#
interface GigabitEthernet0/0/24
port link-type access
port default vlan 20
#
return
六、验证结果
在PC1上使用ipconfig命令查看获取的IP地址等信息。
PC>ipconfig
Link local IPv6 address...........: fe80::5689:98ff:fe14:7494
IPv6 address......................: :: / 128
IPv6 gateway......................: ::
IPv4 address......................: 192.168.1.252
Subnet mask.......................: 255.255.255.0
Gateway...........................: 192.168.1.254
Physical address..................: 54-89-98-14-74-94
