实验八DHCP
实验任务一：PCA直接通过RTA获得ip地址

1. 建立物理连接
   

2. 配置RTA作为dhcp服务器
   [RTA-GigabitEthernet0/0]ip address 172.16.0.1 24
   [RTA]dhcp enable//启动dhcp服务器
   [RTA]dhcp server forbidden-ip 172.16.0.1
   [RTA]dhcp server ip-pool 1
   [RTA -dhcp-pool-1]network 172.16.0.0 24//分配的地址池
   [RTA-dhcp-pool-1]gateway-list 172.16.0.1//分配的网关地址

3. PCA通过dhcp获得ip地址

1. 查看dhcp服务器相关信息
   [RTA]display dhcp server statistics
   Pool number: 1//地址池一个
   Pool utilization: 0.39%
   Bindings:
   Automatic: 1//分配的地址一个
   Manual: 0
   Expired: 0
   Conflict: 0

[RTA]display dhcp server ip-in-use
IP address Client identifier/ Lease expiration Type
Hardware address
172.16.0.2 0036-6539-642e-3831- Apr 20 16:06:33 2018 Auto(C)
6530-2e30-3230-362d-

[RTA]display dhcp server free-ip
Pool name: 1
Network: 172.16.0.0 mask 255.255.255.0
IP ranges from 172.16.0.3 to 172.16.0.254

实验任务二：PCA通过dhcp中继方式获得IP地址

1. 建立物理连接
2. 在设备上配置ip地址及路由
   

注意：vlan2要创建之后，把GE_0/2加入vlan2才能是能vlan2interface.
RTA配置静态路由：[RTA]ip route-static 172.16.1.0 24 172.16.0.1

1. RTA配置dhcp服务器，SWA配置dhcp中继
   [SWA]dhcp enable
   [SWA]interface Vlan-interface 1
   [SWA-Vlan-interface1]dhcp select relay
   [SWA-Vlan-interface1]dhcp relay server-address 172.16.0.2

[RTA-GigabitEthernet0/0]ip address 172.16.0.2 24
[RTA]dhcp enable//启动dhcp服务器
[RTA]dhcp server forbidden-ip 172.16.1.1
[RTA]dhcp server ip-pool 1
[RTA -dhcp-pool-1]network 172.16.1.0 24//分配的地址池
[RTA-dhcp-pool-1]gateway-list 172.16.1.1//分配的网关地址
