ensp学习 vlan / 路由 DHCP动态分配IP
为了减轻TCP/IP网络的规划、管理和维护的负担，解决IP地址空间缺乏问题于是衍生了DHCP这项技术
交换机配置如下
1个交换机+3台PC机
PC1和PC2属于vlan10，PC3属于vlan20
vlan10的ip：192.168.10.1，网关;192.168.10.1
vlan20的ip：192.168.20.1，网关;192.168.20.1
交换机上配置
[Huawei]dhcp enable //开启DHCP
[Huawei]ip pool pool10 //创建全局地址池
Info: It’s successful to create an IP address pool.
[Huawei-ip-pool-pool10]network 192.168.1.0 mask 24 //配置全局地址池下可分配的网段地址
[Huawei-ip-pool-pool10]gateway-list 192.168.1.1 //配置网关地址
[Huawei-ip-pool-pool10]lease day 10 //地址租期
[Huawei-ip-pool-pool10]quit
交换机创建VLAN10
[Huawei]vlan 10
[Huawei-GigabitEthernet0/0/1]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 10
[Huawei]int vlanif 10
[Huawei-Vlanif10]ip add 192.168.1.1 24
[Huawei-Vlanif10]dhcp select global
交换机配置完成后进入PC配置选择DHCP，在PC上使用ipconfig命令是否成功获取到网络地址
路由器DHCP配置如下：
1台路由器+1台PC机 拓扑图如下：
在路由器配置
[r1]dhcp enable
Info: The operation may take a few seconds. Please wait for a
moment.done.
[r1]int e0/0/0
[r1-Ethernet0/0/0]ip add 192.168.1.1 24
[r1]ip pool 1
Info:It’s successful to create an IP address pool.
[r1-ip-pool-1]network 192.168.1.2 mask 24
[r1-ip-pool-1]gateway-list 192.168.1.254
[r1-ip-pool-1]dns-list 8.8.8.8
[r1-ip-pool-1]q
[r1]int e0/0/0
[r1-Ethernet0/0/0]dhcp select global
跟交换机一样配置好PC机的DHCP就可以了
