静态路由（第一步）地址池和DHCP
Dhcp服务器
成为dhcp服务器的条件
必须存在真实物理网卡或连接广播域的真实物理接口必须由合法的ip地址
Dhcp的数据包
dhcp discover dhcp 发现包Dhcp offer dhcp 提供包Dhcp request dhcp 请求包Dhcp ack dhcp 确认包
Dhcp的配置
配置网关地址
[R1]interface g0/0/0
[R1-GigabitEthernet0/0/0]ip address 192.168.1.1 24
开启DHCP服务
[R1]dhcp enable
配置dhcp地址池
[R1]ip pool xatu
Info: It's successful to create an IP address pool.
[R1-ip-pool-xatu]network 192.168.1.0 mask 255.255.255.0
[R1-ip-pool-xatu]gateway-list 192.168.1.1
[R1-ip-pool-xatu]dns-list 8.8.8.8 114.114.114.114
调用
[R1]interface g0/0/0
[R1-GigabitEthernet0/0/0]dhcp select global
新建拓扑
给g0/0/0和g0/0/1端口下放ip 并建两个地址池
pc自动获取ip
