一、网络部署思路

1、拓扑设计—IP地址规划

2、实施
1）底层–所有节点拥有合法的IP地址
：根据所给出的IP网段进行合理子网划分
网段（主机位全为0）192.168.1.0/24
192.168.1.0/27
192.168.1.0/30–192.168.1.4/30–192.168.1.8/30–192.168.1.12/30
192.168.1.16/30–192.168.1.20/30
192.168.1.24/30–192.168.1.28/30（路由器之间预留网段）
192.168.1.32/27 R1 192.168.1.32/28–192.168.1.48/28
192.168.1.64/27 R2 192.168.1.64/28–192.168.1.80/28
192.168.1.96/27 R3
192.168.1.128/27 R4 192.168.1.128/28–192.168.1.144/28
192.168.1.160/27 R5
192.168.1.192/27 (干路预留网段)
192.168.1.224/27（干路预留网段）

给每个接口配置IP地址
[r1]interface GigabitEthernet0/0/1
[r1-GigabitEthernet0/0/1]ip address 192.168.1.33 28
给R3路由器配置DHCP服务
[r3]dhcp enable
[r3]interface GigabitEthernet0/0/0
[r3-GigabitEthernet0/0/0]dhcp select interface
[r3-GigabitEthernet0/0/0]dhcp server dns-list 3.3.3.3
创建环回接口并配置IP地址
[r6]interface LoopBack0
[r6-LoopBack0]
[r6-LoopBack0]ip add 1.1.1.1 24

2）路由–静态/动态 全网可达

3）策略–规则、优化、安全
4）测试
5）排错
3、维护
4、升级— 割接（网工） 扩容（服务器）
